Information Advantage Gained From Surprising Quantum Source
2012-08-06 09:34:56

New research lends hope that a phenomenon called quantum discord could be harnessed to bring quantum technologies within easier reach than expected. The work, by an international team, is published 5 August in Nature Physics. Up until a few years ago, researchers thought that realising quantum technologies would mean harnessing the most difficult-to-tame properties of the quantum world. For example, 'entanglement', the phenomenon referred to by Einstein as spooky-action-at-a-distance, was...

Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks. The results of the experiment, undertaken by a close collaboration of researchers based in Wuerzburg, Munich and Stuttgart, have been published today, Thursday 2 August, in the Institute of Physics and German Physical Society's New Journal of Physics. The single photons were produced using two devices made...

New Device For Quantum Information Processing

A groundbreaking new device from the National Physical Laboratory could help to usher in the long-awaited era of quantum computers Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits (qubits). The research, published in Nature Nanotechnology, shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device's ability to confine...

Study describes greater chances of accessing more reliable information on applications in quantum computing and cryptography Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing. The findings, published in EPJ D´, are so robust that they enable access to the information even when the...

First Heralded Single Photon Source Made From Silicon Demonstrated
2012-06-28 10:53:14

In an important step towards more practical quantum information processing, researchers from the National Institute of Standards and Technology (NIST), the University of California, San Diego; and the Politecnico di Milano in Milan, Italy, have demonstrated the first heralded single photon source made from silicon. This source complements two other recently developed silicon-based technologies–interferometers for manipulating the entanglement of photons and single photon...

USC scientists demonstrate that quantum computing could speed up the way web page ranks are calculated on the ever-expanding Internet Most people don't think twice about how Internet search engines work. You type in a word or phrase, hit enter, and poof — a list of web pages pops up, organized by relevance. Behind the scenes, a lot of math goes into figuring out exactly what qualifies as most relevant web page for your search. Google, for example, uses a page ranking algorithm...

Photons Teleported 60 Miles By Chinese Researchers
2012-05-13 04:46:18

A team of Chinese physicists have shattered the record for quantum teleportation, teleporting photons approximately six times further than the previous best, according to various news reports published Friday. A team of physicists hailing from the University of Science and Technology of China in Shanghai were able to teleport particles more than 97 kilometers, or over 60 miles, said Popular Science's Dan Nosowitz. That smashes the prior standard of more than 10 miles (16-plus...

Expert Predicts Quantum Computing Technology Could Be Near
2012-05-07 04:02:49

A prominent theoretical physicist and the co-author of a book on quantum mechanics believes that research in the field of quantum computing is rapidly progressing, and that the technology is inching ever closer to becoming a reality. In a column written for the Guardian on Saturday, Jeff Forshaw, co-author of the 2011 book 'The Quantum Universe: Everything That Can Happen Does Happen' and a professor at the University of Manchester, said, "Quantum simulations have, in the past year, really...

Theoretical Physicist Michio Kaku: The End Is Near For Moore’s Law
2012-05-01 09:03:39

Brett Smith for Redorbit.com The days of Moore´s Law, which says computer processing capability doubles every 18 months, could be coming to a close according to theoretical physicist Michio Kaku. In a video produced for BigThink.com, Kaku said the smaller and smaller silicon chips that companies are producing might soon reach their processing limits. Once a chip´s layer of silicon reaches the size of about 5 atoms across it will begin to suffer from two particular...
