By exploiting the quantum energy fluctuations in entangled particles, physicists may be able to inject energy in one particle, and extract it in another particle located light-years away. The proposal could lead to new developments in energy distribution, as well as a better understanding of the relationship between quantum information and quantum energy. Citation: Physicist proposes method to teleport energy (2010, February 5) retrieved 18 August 2019 from https://phys.org/news/2010-02-physicist-method-teleport-energy.html Japanese physicist Masahiro Hotta of Tohoku University has explained the energy teleportation scheme in a recent study posted at arxiv.org, called “Energy-Entanglement Relation for Quantum Energy Teleportation.” Previously, physicists have demonstrated how to teleport the quantum states of several different entities, including photons, atoms, and ions. Researchers predict that the principles of teleportation could also extend to molecules, viruses, and other more complex objects. Over the past year, physicists have also been exploring quantum energy teleportation, and Hotta’s latest paper builds on these studies.In quantum energy teleportation, a physicist first makes a measurement on each of two entangled particles. The measurement on the first particle injects quantum energy into the two-particle system, which is possible because there are always quantum fluctuations in the energy of any particle. This energy can then be immediately extracted at the second particle by making a second carefully chosen measurement on that particle. Throughout the process, the energy of the overall system remains the same. As in previous examples of teleportation, the actual particles aren’t teleported since they’re basically identical at the quantum level. Rather, the information they carry is the important part. For this reason, physicists can simply send the information within a particle and not the particle itself. A receiving particle accepts the information from a sending particle, taking on the identity of the sending particle.Hotta’s paper marks the first example of the energy-entanglement relation for the smallest kind of quantum energy teleportation model. As he explains, the findings could enable scientists to explore the foundations of physics: specifically, the relationship between quantum information and quantum energy.“These energy-entanglement inequalities are of importance because they help in gaining a profound understanding of entanglement itself as a physical resource by relating entanglement to energy as an evident physical resource,” he writes. As a story in MIT’s Technology Review explains, these new ideas about entanglement and information could have far-reaching implications: “There is a growing sense that the properties of the universe are best described not by the laws that govern matter but by the laws that govern information. This appears to be true for the quantum world, is certainly true for special relativity, and is currently being explored for general relativity. Having a way to handle energy on the same footing may help to draw these diverse strands together.”last_img read more

Heritage Charkha Museum spin tales of Indian legacy

first_imgIn what comes as the first initiative to link charkha with tourism, BJP president Amit Shah unveiled the Large Steel Charkha and Heritage Charkha Museum – consisting 14 vintage charkhas – at Palika Bazar Park in Delhi’s Connaught Place, amid much fervour and gaiety recently.Hailing this initiative, Prime Minister Narendra Modi, in his special message to Khadi and Village Industries Commission (KVIC) Chairman, said: “As Mahatma Gandhi himself believed, the Charkha is a symbol of our Swaraj and self-reliance. The museum and the monument for the Charkha in the Capital will be a proud tribute to the Charkha’s historic importance in our nation. This will economically empower the lives of several weavers associated with the Khadi industry.” Also Read – Add new books to your shelfKVIC chairman Vinai Kumar Saxena, in his welcome speech, said that Charkha, like the memorial to unknown soldiers, is memorial to the unknown rural masses, who took to the demonstrated ways of self-reliance and dignity of labour following the call of the father of the nation. “The KVIC, in association with New Delhi Municipal Corporation (NDMC), has set up this Heritage Charkha Museum, showcasing 50 to 100 year old charkhas, gifted to KVIC by the owners of these charkhas. The charkha, run by the PM on Oct 18, 2016 at Ludhiana, has also been kept permanently in the museum for display for general public,” he said, adding, “Located in the heart of the Capital, it will certainly catch the eyes of foreign tourists coming here. The sparkling white marble statue of Mahatma Gandhi and the Large Steel Charkha will be visible from all four sides of Baba Kharak Singh Marg.” Also Read – Over 2 hours screen time daily will make your kids impulsiveBJP President Amit Shah said that from time immemorial Charkha had been the symbol of economic empowerment of our nation. “It is really a commendable job from the part of KVIC and NDMC that both the organisations have come up with a novel mission with economic model to promote tourism. I hope that the spinning wheel would symbolise the mission of our Prime Minister Narendra Modi’s ‘Make in India’.” Corroborating similar views, Kalraj Mishra, Union Minister MSME, said that Charkha would script the story of economic Independence of India in coming days. In his thanksgiving note, New Delhi Municipal Council (NDMC) Chairperson Naresh Kumar said that it would not only give a direct exposure to the vision to the New Delhi area about ‘Charkha’– a symbol of nation’s prosperity – but also to values and preserve the rich heritage of our composite culture. “Charkha is not only a symbol of simplicity and economic freedom by Swadeshi but also a symbol of peace and harmony, hence it will promote Prime Minister’s vision for ‘Make In India’,” he said, adding, “The NDMC will deliver its best to up-keep and maintain the Charkha and Heritage Museum spin tail of Indian legacy. The Council is striving hard for transforming the efficient, effective and livable New Delhi area through the intervention of modern digital technology.” The 2.5 tonne large steel charkha is made of high-quality chromium nickel stainless steel and is corrosion resistant, non-magnetic and not hardenable by heat. The order to make this 12 feet tall and 25 feet long spinning wheel was given to Prayog Samiti, KVIC unit, near Sabarmati Ashram in Gujarat. The high quality stainless steel for the charkha was donated by Steel Authority of India (SAIL).On this occasion, besides gifting 500 new model eight-spindle charkhas – with a cost of approximately Rs 70 lakh – to the women spinners of nine states, a live charkha demonstration was also held by 10 women inmates of Tihar Jail. A film on Mahatma Gandhi was also screened, after a philatelic exhibition on ‘Father of the Nation’.last_img read more
