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...

Nature Nanotechnology: On the way to the quantum computer The alphabet of data processing could include more elements than the "0" and "1" in future. An international research team has achieved a new kind of bit with single electrons, called quantum bits, or qubits. With them, considerably more than two states can be defined. So far, quantum bits have only existed in relatively large vacuum chambers. The team has now generated them in semiconductors. They have put an effect in practice,...

IBM revealed on Tuesday that it has achieved a major advance in quantum computing that will allow engineers to begin working on a full-scale quantum computer. The new breakthrough allows scientists to reduce data error rates in elementary computations while maintaining the integrity of quantum mechanical properties in quantum bits of data. Mark Ketchen, the manager of physics of information at the IBM's TJ Watson Research Center, said the creation of quantum computers would mean data...

[ Watch the Video ] A team of Australian and American researchers announced on Sunday that they had created a working transistor from a single phosphorus atom embedded precisely in a silicon crystal. The transistor was completed by physicists at the University of New South Wales (UNSW), the University of Melbourne, and Purdue University, and according to a UNSW press release, this "remarkable feat of micro-engineering“¦ uses as its active component an individual phosphorus...

A report published this week indicates that a new, secure, high-speed computing technology based on quantum physics is compatible with “cloud computing” and could eventually revolutionize the world of computers as we currently understand it. Blind quantum computing, as it´s being called, exploits uncertainties in quantum physics to carry out ultra-fast computations. And according to an international team of researchers who published their work in this week´s issue of...

Breakthrough in coordinating electrons advances goal of quantum computing An international team of researchers including scientists at Princeton University have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers. Until recently, the best attempts at such control lasted for only a fraction of a second. But researchers Stephen Lyon and Alexei Tyryshkin have found a way to...

Pitt physicists able to obtain higher-precision measurements with “single-electrons in-diamond” approach Quantum computing–considered the powerhouse of computational tasks–may have applications in areas outside of pure electronics, according to a University of Pittsburgh researcher and his collaborators. Working at the interface of quantum measurement and nanotechnology, Gurudev Dutt, assistant professor in Pitt´s Department of Physics and Astronomy in the...
