Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing. The metamaterial - layers of silver and titanium oxide and tiny components called quantum dots - dramatically changes the properties of light. The light becomes "hyperbolic," which increases the output of light from the quantum dots. Such materials...

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...

A team led by an Ames Laboratory scientist develops new technique for solid-state quantum information processing Scientists have overcome a major hurdle facing quantum computing: how to protect quantum information from degradation by the environment while simultaneously performing computation in a solid-state quantum system. A group led by U.S. Department of Energy´s Ames Laboratory physicist Viatsheslav Dobrovitski and including scientists at Delft University of Technology; the...

Image 1 - Researchers Create Quantum Computer In Diamond
2012-04-06 04:31:03

A girl's best friend has stepped into the digital age as scientists from the University of Southern California have built a quantum computer inside a diamond. The scientists reported in the journal Nature on Thursday that their diamond quantum computer system features two quantum bits, or qubits, made of subatomic particles. Qubits are able to encode a one and a zero at the same time, compared to traditional computer bits, which encode distinctly either a one or a zero. Being able to...

Model simulates closer control over the transport of information-carrying electrons Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in EPJ B´. This study, led by scientists from Zhejiang University, Hangzhou, China, and the Centre for Computational Science and Engineering at the National University of Singapore, could have implications for quantum...

Researchers have discovered a new way in which computers based on quantum physics could beat the performance of classical computers. The work, by researchers based in Singapore and the UK, implies that a Matrix-like simulation of reality would require less memory on a quantum computer than on a classical computer. It also hints at a way to investigate whether a deeper theory lies beneath quantum theory. The finding emerges from fundamental consideration of how much information is needed to...
