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...

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...

New device, developed by team of engineers led by Professor Amr Helmy (ECE), could bring quantum computing to your home or office In the age of high-speed computing, the photon is king. However, producing the finely tuned particles of light is a complex and time-consuming process, until now. Thanks to the work by a team of engineers led by Professor Amr Helmy of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering, a novel solution has been identified that will...

NIST Physicists Benchmark Quantum Simulator With Hundreds Of Qubits
2012-04-25 11:32:05

Physicists at the National Institute of Standards and Technology (NIST) have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits)–10 times more than previous devices. As described in the April 26 issue of Nature*, the simulator has passed a series of important benchmarking tests and scientists are poised to study problems in material science that are impossible to model on conventional computers. Many important problems in...

Quantum Physics Mimics Spooky Action Into The Past

Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist. Their results will be published this week in the journal...

Quantum Network Created Based On Interfaces Between Single Atoms And Photons
2012-04-12 09:37:30

Brett Smith for Redorbit.com Quantum physicists have made a leap forward in subatomic particle communication by connecting two separate labs 21-meters apart using two atoms and a photon, according to a report published in the April 12 issue of Nature. A group from the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany said they have demonstrated the ability to construct a basic two-node network that could be expanded because of its high efficiency and fidelity....

A research team led by University of Toronto Professor Hoi-Kwong Lo has found a new quantum encryption method to foil even the most sophisticated hackers. The discovery is outlined in the latest issue of Physical Review Letters. Quantum cryptography is, in principle, a foolproof way to prevent hacking. It ensures that any attempt by an eavesdropper to read encoded communication data will lead to disturbances that can be detected by the legitimate users. Therefore, quantum cryptography...
