(PhysOrg.com) — One of the subjects of immense interest to scientists (and non-scientists as well) is the development of quantum computers. However, there are many challenges associated with quantum computing. One of the difficulties to achieving practical quantum computing is related to the way the quantum bits (qubits) that make up a quantum computer are connected together. “The easiest way to couple superconducting qubits is via fixed coupling, where the coupling strength does not change,” Bialczak says. “Many experiments done with superconducting qubits so far have been with fixed coupling, but there are lots of problems with fixed coupling architectures because they are difficult to scale up to many qubits.”Bialczak worked with a team at UC Santa Barbara to look for a way around the problems caused by fixed coupling. They developed a novel tunable coupler design that has the potential to be scalable, possibly improving current quantum computer designs. The team’s work can be found in the Physical Review Letters article “Fast Tunable Coupler for Superconducting Qubits.”With fixed coupling, Bialczak explains, it is easy to couple the qubits so that they can exchange information, but keeping the qubits from interacting with each other is difficult and causes errors in single-qubit operations and measurement. On top of that, problems with fixed coupling multiply as you add more qubits. “As you increase the number of qubits,” Bialczak says, “it gets increasingly difficult to isolate an individual qubit from the others. It’s like having a room full of people and wanting to isolate each person from the conversation of the other people. You won’t be able to do so because there are so many people…each personal will hear one or more of the other persons’ [conversations].”In order to overcome these issues, the team at UC Santa Barbara developed a method of fast tunable coupling. “With tunable coupling, you can directly turn off the interaction between qubits,” Bialczak says, “The coupler can also arbitrarily tune the coupling strength on nanosecond timescales allowing for fast qubit interaction times while minimizing errors in single-qubit operations and measurement.” For realistic quantum operations, a practical tunable coupler is needed. Such a coupler would need to be tuned quickly, on the order of nanoseconds. Additionally, large on/off ratios are required, as well as scalability so that many qubits can be coupled. “Previous demonstrations of tunable coupling were able to show one or more of the above in a given device, but were unable to combine all the criteria in one device, making them of limited use in realistic quantum computing experiments,” Bialczak points out. The UCSB team hopes that their new tunable coupler will satisfy all these criteria.In order to create the tunable coupler circuit, two superconducting qubits are coupled using a fixed negative mutual inductance. This mutual inductance is shunted with a current-biased Josephson junction. The junction acts as a tunable positive inductance and can therefore cancel out the fixed coupling due to the mutual inductance.“Our coupler also has the added feature of being modular and being able to couple elements over large spatial distances. We can also couple them to other devices and possibly even to qubits from other architectures,” Bialczak says.Right now, the coupler is being used to develop a new measurement scheme that doesn’t destroy prepared quantum states. “This is commonly called a quantum non-demolition measurement scheme,” Bialczak says.Bialczak has great hopes for the applications of this coupler. “We feel this is a general modular superconducting circuit element that can have many applications, even outside of quantum computation.” Copyright 2010 PhysOrg.com.

Munro, et al. “Quantum communication without the necessity of quantum memories.” Nature Photonics DOI: 10.1038/NPHOTON.2012.243 Illustration of the new quantum communication scheme, where information is directly transmitted from one node to another using a transmitter unit and a receiver unit. The scientists calculated that the new approach could potentially enable communication rates several orders of magnitude faster than other approaches. Credit: W. J. Munro, et al. ©2012 Macmillan Publishers Limited In such a system, the performance is inherently limited by the time it takes to establish entanglement between nodes. This time is at best the classical signaling time between the nodes, but with many schemes it is even longer, and increases as network size increases. Since the qubits that store the quantum information are unstable and quickly decohere, quantum memories are required to store quantum information for milliseconds or longer while they wait for entanglement. The result is a theoretical limitation on speed due to the system’s design and the need for additional components – quantum memories – to enable a functioning network.In a new study published in Nature Photonics, scientists from Japan and the UK have presented an alternative design for a quantum communication network that requires neither entanglement between nodes nor quantum memories. Instead, the scheme transmits quantum information in encoded form directly across the network, using devices that act as quantum repeaters (without entanglement) to transmit and receive information between each other. Because this approach doesn’t use entanglement, the communications rate is not limited by the conventional restraints that limit the rates of entanglement-based approaches.”The significance of this work is that we have removed the need for classical messages to herald the generation of entanglement between adjacent nodes,” coauthor Bill Munro of NTT Basic Research Laboratories in Kanagawa, Japan, and the National Institute of Informatics in Tokyo, Japan, told Phys.org. “This classical signal means our qubits at the remote nodes had to wait until it could be found out whether they were entangled or not. With repeater nodes separated by tens of kilometers, this waiting time was on the order of hundreds of microseconds. This means we needed long-lived quantum memories (milliseconds or longer life times) to store the information (entanglement) that was in those qubits. Copyright 2012 Phys.org All rights reserved.

Citation: Quantum communication without entanglement could perform faster than previously thought possible (2012, October 29) retrieved 18 August 2019 from https://phys.org/news/2012-10-quantum-entanglement-faster-previously-thought.html In order to build a quantum internet – a network that is faster and more secure than the current internet – the key is the ability to transmit quantum information between remote quantum computers (i.e., nodes). The most familiar approach involves entangling the links between nodes and then using quantum repeaters at intermediate locations to provide entanglement swapping, extending the range of entanglement across km-long networks.

Instead we send an encoded signal between the nodes. Once the message has left one node to be transmitted to the next node, the resources available in the first node are freed up and the next message can be sent down the channel (even before the second node has received the first message), thus increasing the rate at which information can be transmitted. Entanglement-based approaches cannot do this, so their only route to higher communication rates is by paralleling resources within the node.”In the new approach, information is stored in matter qubits, such as electron spins, in the transmitter and receiver units. The transmitter, which contains a single-photon source, transfers the information from the matter qubits to the photonic qubits. Then it sends the photonic qubits down an optical fiber to the receiver, which contains a single-photon detector. The receiver operates in reverse, transferring the information from the photonic qubits back to matter qubits. Unlike traditional schemes, the new scheme doesn’t require entanglement between the matter qubits at the two remote nodes. As soon as the transmitter moves the information from the matter qubit to the photonic qubit, the matter qubit is no longer needed, so quantum memory is not required to store its information. After the completion of one cycle, the final matter qubit is checked for errors using a redundant quantum parity code. Since channel losses and source/detector inefficiencies are inevitable, quantum states can easily be degraded during quantum communication. The error correction code protects against this degradation by measuring the states of several matter qubits that all carry the same information. The physicists showed that this encoding process can tolerate photon loss in excess of 50% in the quantum channel between nodes, which allows for nodes to be spaced further apart than usually thought.After the error correction code verifies successful transmission of a qubit, the receiver then acts as a transmitter and sends the information on to the next node in the network. The scientists calculated that the scheme could transmit data at a rate of 107 quantum states per second, and operate over a distance of at least 17 km between nodes. With 48 nodes, quantum information could be transmitted over 800 km with a success probability of greater than 98%. The scientists calculated that the new approach could potentially enable communication rates several orders of magnitude faster than other approaches. In addition to speed, the new scheme also has other routing advantages.”Our solution also makes it very easy to see how one can send information on a more complicated quantum network,” Munro said. “Each node would have a telephone-like number and then we can think of telephone-like exchanges that route the information to where it needs to go. The node that sends the original message does not need to know the route to the final destination. Instead it just needs to get to a local exchange which can route it through the chain using country, region, and city parts of the telephone-like number.”In the future, the researchers plan to tackle some of the technical challenges facing the new quantum communication scheme.”Our future plans are an experimental implementation of this approach,” Munro said. “Currently we are working on ways to improve our local gates within our physical system – a necessary step to showing our new communication scheme.”The key requirement in this new approach is the need for efficient quantum gates within the repeater node,” he added. “In the normal entanglement-based approach, we can work with gates that fail a lot of the time in a heralded way. Currently, efficient quantum gates are experimentally challenging to achieve but they need to be achieved if distributed quantum computers are going to be achieved.” Journal information: Nature Photonics

Kolkata: The man found hanging from an electricity tower in Purulia had committed suicide as per the post-mortem examination, police said on Sunday as life was hit in the area due to the 12-hour strike called by the BJP to protest against the alleged murder of its party workers. Soon after taking charge on Sunday morning, the new Superintendent of Police of Purulia district, Akash Magharia, said: “There was a death of a person at Dava village in Balarampur on Saturday. He was found mysteriously hanging from a tower of high tension wire. We had initiated an unnatural death case and the body was sent for an autopsy that was carried out by a board of five doctors. We have received the report. The board of doctors has clearly stated in the report that the death was due to asphyxia due to hanging and suicidal in nature.” Also Read – Heavy rain hits traffic, flightsWith the police getting the opinion of the board of doctors, they have become sure that Dulal had committed suicide and there was no foul play behind it as claimed by BJP.Partha Chatterjee, secretary general of the Trinamool Congress, said: “The autopsy report showed that it was a suicide. It shows that such controversy over it was created just to malign the state government.”It may be mentioned that Dulal had left home on Friday evening and went missing since then. His motorbike was found on Friday night itself. But his body was found hanging on Saturday morning. Locals had agitated and the police had to chase them away by raising their lathis to ensure that the law and order situation remained in order. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe BJP had called a strike in Balarampur on Sunday. But people went out for their work as usual without caring much. There were allegations of threats to the local residents asking them not to come out of their houses and to keep shops shut. Starting from women to middle-aged men, all went out of their houses without paying any heed to the warnings. There were sufficient state-run buses and it helped to ensure a normal day in Balarampur. However, there was police patrolling in sensitive places to avoid any untoward incident that might occur once again leading to deterioration of the law and order situation.The police are also maintaining a strict vigil in the district so that no attempts to disturb peace can be achieved.
The accused Amer Sarfaraz alias Tamba had filed the application before Additional District and Sessions Judge Lahore Nasir Rana seeking bail in the case.The judge on Saturday dismissed his plea observing the incident had taken place in “broad daylight” in the presence of other prisoners and the jail authorities besides the prosecution had also produced sufficient incriminating evidence against Tamba.Tamba in his application said he had been implicated in the case as he was not present at the barrack of Sarabjit when he came under attack.

The murder trial began in January, 2014, and subsequently the two alleged killers – Tamba and Muddassar Bashir – were indicted. Both accused denied the murder charges when they were charge-sheeted.However, earlier they had confessed to the murder of the Indian death row prisoner before a one-member judicial commission constituted to probe the murder.They said, “We wanted to take revenge from him (Sarabjit) for killing Pakistanis in bomb blasts in Lahore and Faisalabad”. The commission’s report has also been submitted to the trial court.The Human Rights Commission of Pakistan had labelled Sarabjit’s murder as a “planned one”.Sarabjit was sentenced to death on spying charges and for killing at least 14 Pakistani citizens in bomb blasts in Punjab province in 1990. His family however said that he was a victim of mistaken identity and had inadvertently strayed across the border.

To commemorate the International Day of the Girl Child on October 11, a UN-declared international observance day to support greater opportunities for girls and end gender discrimination, teenage girls from marginalised communities stepped into the roles of traffic policemen and manned the traffic in the national Capital.European Union Ambassador to India, Tomasz Kozlowski inaugurated the takeover and distributed badges to the girls. He said, “Ensuring that girls feel respected and valued in society is the first step to breaking down the barriers of discrimination. Today, on International Day of the Girl Child, we remember that empowering girls and women is not just our moral duty, it is also the solution to many of the greatest challenges we face in the quest for development and peace: Investing in girls is investing in peace and prosperity”.

They were assisted by traffic police personnel, most of whom were women. They also displayed signage and posters on gender equality as well as girls’ rights. Passersby were handed stickers with the message ‘Be the Driver of Change’.The celebration of the International Day of Girl Child is part of a 3-year collaboration between the European Union (EU) and Plan India for promoting gender equality and combating discrimination against the girl child. The EU currently funds 3 large initiatives on the rights of the girl child in India, with a specific focus on eliminating sex-selective abortions.

By occupying such spaces and places where they are rarely seen or heard, it is a step towards promoting gender inequality and claiming their rights.”Besides manning traffic, the girls also took over important roles even in corporate houses, media publications and radio stations for a day, last week to commemorate International day of the Girl Child. Going forward, 10 metro stations in Delhi will also have signage and people will be requested to pledge their support for a safer Delhi, from October 11-20. Plan India, a member of Plan International Federation, is a nationally registered independent child development organisation committed to creating a lasting impact in the lives of vulnerable and excluded children, their families and communities. Plan International celebrates this day to support the movement for girls’ rights and development so that girls everywhere can learn, lead, decide and thrive.Champa, studying for a bachelor’s degree in Liberal Arts and Sciences, comes from a family of six. She has been involved with Plan India as a youth advocate for the past four years, ensuring that her community is safer for girls and that they are more aware of their rights. She said, “We must work together to ensure girls and young women are aware and have access to justice. Informed and empowered girls can stand firm against injustice and demand their rights. Doing this together allows us to share our challenges and innovative ideas to overcome them.”
Posts on Twitter and Instagram often promote “bonespiration” and “thinspiration” – women’s bodies featuring protruding bones and pencil-thin limbs – which encourage eating disorders such as anorexia, a study warns. Researchers from University of Exeter in the UK show that among thousands of account holders on social media, the images of protruding bones are almost exclusively posted by young women.This so-called “bonespiration” content features selfies by young women of their skeletal bodies featuring protruding collar bones, hip bones and spines in a variety of poses, researchers said. Also Read – Add new books to your shelfIts purpose is to boast about a skeletal appearance and inspire others to achieve the same emaciated look, they said.The study, published in the Journal of Eating Disorders, analysed 730 images posted.It found 26 per cent of images showed hip bones, 23 per cent showed jutting ribs, and 22 per cent showed protruding collarbones. Six per cent of photographs analysed depicted the spine.Academics fear that social media has replaced the pro- anorexia websites, and are becoming an easy to access way of encouraging eating disorders, such as anorexia, researchers said. Also Read – Over 2 hours screen time daily will make your kids impulsiveThey fear efforts to ban the images would lead to others with different hashtags appearing within days.The study also found more mainstream twitter accounts such as ‘thinspiration’, which features photos of thin celebrities, also depict young people with protruding ribs collar bones and spines.Researchers also noted a small sub group of people posting skeletal images with the hashtag ‘fitspiration’, which is dedicated to inspiring supposedly healthy bodies. The sites are being used to promote extremely unhealthy body types and are increasing pressure on teenage girls to try to become extremely thin, while contributing to a distorted view of their own body, researchers said.”Anorexia and extreme weight loss is a serious social and medical problem,” said Catherine Talbot, a psychologist at the University of Exeter.”To tackle this social contagion we need to be aware of the social media platforms being used by young people – mainly girls and young women – which is encouraging extreme weight loss. This behaviour could seriously damage their psychological and physical health,” she said.”Teenagers need to be taught about positive body image in schools and we need to build resilience,” Talbot added.
Kolkata: The Election Commission (EC) is trying to address the connectivity issue for monitoring each and every polling station for ensuring a streamlined and peaceful election in West Bengal, an official said here on Friday. “In West Bengal, the number of polling stations with voice and internet shadow zone are respectively 159 and 1,019. Efforts are underway to reduce the number of polling stations falling under the shadow zone,” Additional Chief Electoral Officer, West Bengal, Sanjay Basu told reporters.

Hot-brewed coffee has higher levels of antioxidants than cold brew, which are believed to be responsible for some of the health benefits of the popular drink, a study has found. The study, published in the journal Scientific Reports, also found that the pH levels or acidity indicator, of both hot and cold coffee were similar, ranging from 4.85 to 5.13 for all coffee samples tested. Coffee companies and lifestyle blogs have tended to tout cold brew coffee as being less acidic than hot coffee and thus less likely to cause heartburn or gastrointestinal problems, said researchers from Thomas Jefferson University in the US. Also Read – Add new books to your shelfWhile the popularity of cold brew coffee has soared in recent years – the US market grew 580 per cent from 2011 to 2016 – the researchers found almost no studies on cold brew, which is a no-heat, long-steeping method of preparation. At the same time, there is well-documented research that hot-brewed coffee has some measurable health benefits, including lower risk of some cancers, diabetes and depression. While the overall pH levels were similar, the researchers found that the hot-brewed coffee method had more total titratable acids, which may be responsible for the hot cup’s higher antioxidant levels. “Coffee has a lot of antioxidants, if you drink it in moderation, research shows it can be pretty good for you. We found the hot brew has more antioxidant capacity,” said Megan Fuller, an assistant professor at Thomas Jefferson University. Researchers said, coffee drinkers should not consider cold brew a “silver bullet” for avoiding gastrointestinal distress.
Kolkata: The state Tourism department is coming up with a District Tourism Committee (DTC) in all 23 districts across the state, to ensure a hassle-free travel experience for domestic as well as international tourists. “The DTC will have five members with the District Magistrate (DM) as the chairman, the District Information and Cultural Officer (DICO) as member secretary, another senior government official and two eminent persons from the district. The committee will ensure that tourists in their respective districts face no hassle during their visit and stay,” said state Tourism minister Goutam Deb, while delivering his Budget speech for 2019-20 at the state Assembly on Tuesday.

According to the enhancement, the MLAs will get an approximate allowance of Rs 60,000 instead of Rs 30,000 and the allowance of the ministers, including the Chief Minister, will be Rs 90,000 instead of Rs 60,000 per month.

It may be mentioned here that this is the third time the Mamata Banerjee government has decided to increase the emoluments of the MLAs and ministers. Prior to this, when the state Assembly passed the West Bengal Salaries and Allowances (Amendment) Bill, 2017, the salary of the Chief Minister was increased to Rs 27,001 from Rs 8,500. The ministers’ salary was increased to Rs 22,000 from a meagre Rs 7,500, while the salary of the ministers of state was raised to Rs 21,900 from Rs 7,300. Similarly, the salary of the MLAs was hiked to Rs 17,500 from Rs 5,000. The salary of the Leader of Opposition was also increased to Rs 22,000 from Rs 10,500. In 2011, when Mamata Banerjee came to power, the allowance of members of Assembly was increased as well.
Prints of the famous Cottingley fairy photographs recently came to auction. Although initially expected to fetch £2,000 ($2,600), they ended up selling for over £20,000 ($26,000). The photographs have been famous ever since they were published in the 1920 Christmas edition of The Strand.The world was aghast to see pictures, taken by two young girls, apparently proving the existence of fairies.Cottingley Fairies pictures. Photo by Johnny Green – PA Images/PA Images via Getty ImagesElsie Wright, aged 16, and nine-year-old Frances Griffiths were cousins. When they took the first photographs, Frances was visiting Elsie, who lived in the village of Cottingley, England.The girls used to play a lot by a nearby stream. This annoyed Elsie’s mother since they often came back bedraggled, but the girls insisted they went there to see the fairies.When no one believed the cousins, Elsie took her father’s camera the next time they went to play. When they came back, Elsie’s father, Arthur, developed the photographs they’d taken.Among them was one showing Frances sitting with four fairies dancing in on a rock in front of her.Frances and the Leaping Fairy.Arthur knew his daughter was creative and assumed the fairies were merely cardboard cut-outs. But two months later, the girls took another photograph which Elsie’s mother, Polly, was convinced was authentic.In mid-1919, Polly attended a meeting of the Theosophical Society in Bradford. The subject under discussion was “fairies,” so she took the pictures along.The photographs were subsequently exhibited at the Society’s annual conference, and so they came to the attention of the public.Cottingley Beck, where Frances and Elsie claimed to have seen the fairies Photo by Paul Glazzard CC BY-SA 2.0Edward Gardner was a leading member of the Society. He sent the prints, along with the original glass-plate negatives, to Harold Snelling, a photography expert.Snelling’s response was that “the two negatives are entirely genuine, unfaked photographs… [with] no trace whatsoever of studio work involving card or paper models.”However, Snelling made it clear that he wasn’t suggesting that the photographs proved the existence of fairies, only that they hadn’t been tampered with, but showed “whatever was in front of the camera at the time.”Edward.

After three evaluations, it seemed that only one came back with the opinion that there was “some evidence of faking.”The second of the five photographs, showing Elsie with a winged gnome.Gardner went to visit Elsie and her family. Arthur Wright said that he’d been so sure the photographs were fake that he’d searched Elsie’s room and the stream in an effort to find evidence. But he’d failed to find anything incriminating.Gardner wanted to prove the photographs beyond doubt. To that end, Frances was invited to stay with the Wrights again for the summer of 1920.At the end of July, Gardner returned with two Kodak cameras and 24 photographic plates.Sir Arthur Conan Doyle.He gave each girl a camera and some brief instructions on how to get the best pictures. However, he assured them “[i]f nothing came of it at all… they were not to mind a bit.” He did not want them to feel under pressure.The girls insisted that the fairies would not come if others were watching, so they were left alone.They took several pictures over that time, including those entitled Fairy offering Posy of Harebells to Elsie, Frances and the Leaping Fairy, and Fairies and their Sun-Bath.One of Claude Arthur Shepperson’s illustrations of dancing girls, from Princess Mary’s Gift Book.Doyle sought permission from Arthur Wright to publish the first two pictures as part of his article on fairies which he was writing for The Strand. Arthur gave his consent. Doyle protected their identity by naming the family as “the Carpenters” in his article.The photographs had a mixed reception. Maurice Hewlett, a historical novelist and poet, stated in an article for John O’London’s Weekly: “knowing children, and knowing that Sir Arthur Conan Doyle has legs, I decide that the Miss Carpenters have pulled one of them.”Comparison of Cottingley Fairies and illustrations from Princess Mary’s Gift Book.In 1921, Doyle published the later pictures in The Strand, inspiring similar reactions. In August of that year, Gardner took another trip to Cottingley.This time, Gardner took with him Geoffrey Hudson, a noted clairvoyant. Neither Elsie nor Frances claimed to see any fairies during that visit. In contrast, Hudson claimed he saw them everywhere.After 1921, interest in the photographs died down. In 1966, Elsie was interviewed by a reporter from The Daily Express. She didn’t say the photographs were fake but suggested that what the camera had succeeded in photographing might have been a figment of her imagination. She gave the same story again in another interview in 1971.Elsie Wright in 1920, picture printed in the American edition of the 1922 book ‘The Coming of the Fairies’ by Sir Arthur Conan Doyle. Author is not precised.Finally, in 1983, the cousins admitted that the pictures were fake. Elsie had copied pictures of dancing girls from Princess Mary’s Gift Book and drawn wings on them. The two girls had then cut the drawings out and stood them upright using hatpins, which they later disposed of in the stream.However, the girls disagreed on the authenticity of the fifth photograph, the last one they took. Elsie maintained it was a fake, but Frances said: “It was a wet Saturday afternoon and we were just mooching about with our cameras and Elsie had nothing prepared. I saw these fairies building up in the grasses and just aimed the camera and took a photograph.”Frances Griffiths in 1920.Geoffrey Crawley, in a letter to The Times published in April 1983, suggested how both girls might be telling the truth. He reasoned that the photograph was “an unintended double exposure of fairy cutouts in the grass.”In 1985, for the television program Arthur C. Clarke’s World of Strange Powers, Elsie admitted why they had carried on the ruse for so long: they were embarrassed to admit the truth after fooling the famous author.The fourth photograph – Fairy Offering Posy of Harebells to Elsie.“Two village kids and a brilliant man like Conan Doyle – well, we could only keep quiet… I never even thought of it as being a fraud – it was just Elsie and I having a bit of fun and I can’t understand to this day why they were taken in.”Geoffrey Crawley sold his Cottingley fairy collection to the National Science and Media Museum in Bradford. The items included prints of the photographs, two of the cameras used, watercolors painted by Elsie, and a letter admitting to the hoax written by Elsie.The fifth and last photograph of the Cottingley Fairies – Fairies and Their Sun-Bath.On October 4, 2018, two of the prints used by Gardner in his lectures came under the hammer at Dominic Winter Auctioneers in Cirencester, England. Since these were only prints, rather than the original photographs, they were given a conservative estimate of £700-£1,000 ($900-$1,300) each.In fact, the print of Elsie with a gnome sold for £5,400 (around $7,000) while the other print, showing Frances with the fairies sold for £15,000, or almost $20,000.Read another story from us: Marie Antoinette’s Dazzling Jewelry Made Public for the First Time EverWith such a price tag, it seems fair to say that the Cottingley photos fascinate the public as much today as they did in 1920.
Christmas constitutes one of the most important holidays in the Christian world. The date which symbolizes the birth of Jesus is celebrated globally and has been recognized as such since the early Middle Ages. Although primarily a religious holiday, over time it has become more of an occasion for a family gathering, exchange of presents and colorful decorations.In the United States, this image of Christmas was created in the years following WWII. The period of prosperity in the 1950s which launched the U.S. economy gave Christmas accessories such as mass-produced ornaments, and Christmas trees supplied on a large-scale and available to everyone.An aluminum tree decked with baubles a single color.

Which Santa do you think will win this race?The post-war period also introduced a number of artificial options to substitute bringing a live tree indoors, using new materials such as aluminium and PVC plastic, which came in a range of colors.Artificial trees were in the spotlight in the late-1950s, for they fit nicely with the streamlined home decor of the emerging Space Age style.Toppers and stands also became increasingly popular, with a variety of them on the market. The most popular was the lit-from-within style, which provided additional lighting to the already shining mixture of bubble lights and reflective ball ornaments.It all added up to the merry and joyful image of Christmas as a family holiday, which became increasingly popular as a consumer holiday as well.

Lovers of classical art flock to Italy to view the many amazing works of art to be found there. Italy is the home of some of the most famous pieces of sculpture in the world, but it’s also home to other, less famous pieces that are equally stunning. In the historic center of Naples lies the Cappella Sansevero, a chapel full of some of the most beautiful and intricate sculpture of the 18th century, commissioned by one of the most controversial figures of era, Raimondo di Sangro.Cappella Sansevero Napoli. Photo by Hotepibre CC BY-SA 2.5The chapel itself was originally built late in the 16th century for the tombs of the di Sangro family. It wasn’t until the 18th century that Raimondo di Sangro gave it the refit it still enjoys to this day.The chapel houses a stunning array of nearly thirty works of art, but arguably the most remarkable pieces in the chapel are the central statue, Veiled Christ, or Christ Veiled under a Shroud, and the sculptures that surround it.Cappella Sansevero. Photo by David Sivyer CC BY-SA 2.0The reclining Christ lays on a carved plinth, covered with what appears to be a sheer veil which softens, but doesn’t obscure the body underneath. Amazingly, as with the other central statues in the chapel, the veil and figure are carved from one piece of marble.It was created by Giuseppe Sanmartino, who finished it 1753. Di Sangro had originally hoped to have the piece carved by Antonio Corradini, who was responsible for Modesty, another of the sculptures in the chapel, but Corradini died in 1752, having only made a scale model of the piece.Il Disinganno (Deception) by Francesco Queirolo. Photo by David Sivyer CC BY 2.0The effect of sheer fabric carved out of marble makes Sanmartino’s work one of the most impressive in the world. The statues which surround the Veiled Christ all represent various virtues. Of these, perhaps the most astonishing is Release From Deception by Francesco Queirolo, also known as Disillusion.Deception (close up). Photo by David Sivyer CC BY-SA 2.0The work is dedicated to di Sangro’s father, Antonio, who turned to a sybaritic lifestyle after the death of his wife, according to Lonely Planet. Antonio di Sangro came to repent his ways later in life and joined the priesthood as a way to atone for his misdeeds.Veiled Christ.

There’s a globe at his feet, with an open book resting on top of it.The tableau symbolizes a man who is set free of sin, which is represented by the net. The winged angel has a flame on its head, representing the human intellect, and it’s helping to free the figure while pointing down at the globe representing worldly desires. The book on top of the world is the bible, and carving at the statue’s base tells the story of Jesus restoring sight to the blind.Cappella Sansevero, Naples, Italy. Photo by David Sivyer CC BY 2.0Without question, the most remarkable feature of the sculpture is the net that surrounds the figure within. According to BoredPanda, not only does it surround the man almost entirely, but the work itself is incredibly intricate, showing the details of the rope and the knotting very clearly.Cappella Sansevero. Photo by David Sivyer CC by SA 2.0The net is so delicate that it’s believed that when it was time for the completed statue to be smoothed with pumice (the step that gives marble work that smooth finish), Queirolo had to do the work himself, since none of the local craftsman were willing to risk breaking it.Statue of Modesty. Photo by David Sivyer CC BY-SA 2.0Raimondo di Sangro was a very interesting and controversial figure. He was the seventh Prince of Sansevero, born in 1710. In addition to being a Freemason, he was also an inventor, scientist, soldier, alchemist, and writer. His mother died when he was only about 10, and he spent the 10 years after her death being educated at the Jesuit College in Rome.Cappella Sansavero. Photo by David Sivyer CC by SA 2.0According to Directory Rex, di Sangro’s interests in science and inventing led him to increasingly esoteric studies laced with alchemical and Masonic teachings. He joined the Freemasons in 1750, but later renounced freemasonry after the pope condemned the group.Cappella Sansevero. Photo by David Sivyer CC BY 2.0Despite the renunciation, di Sangro began to break with the Catholic Church, and his studies continued to become more recondite and occult-oriented. Even though he had earned some renown as a philosopher and inventor, rumors of black magic and bizarre experiments with kidnapped subjects swirled around him.Cappella Sansevero. Photo by David Sivyer CC BY-SA 2.0The latter rumor is supported by “Adam and Eve”, two sets of human remains in the basement of the chapel, which are not only the bodies’ bones, but each figure has its complete nervous system still attached.Read another story from us: Symbolic to the Max – The Eerie Story of the Veiled VirginThe Chapel of Sansevero embodies both the mystic and the religious aspects of a complex man.
