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...

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...

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...

IBM Makes Strides In Quantum Computing Technology
2012-02-29 05:13:35

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...

Image 1 - Quantum In The Cloud?
2012-01-20 14:20:14

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...

A new paradigm in quantum information processing has been demonstrated by physicists at UC Santa Barbara. Their results are published in this week's issue of Science Express online. UCSB physicists have demonstrated a quantum integrated circuit that implements the quantum von Neumann architecture. In this architecture, a long-lived quantum random access memory can be programmed using a quantum central processing unit, all constructed on a single chip, providing the key components for a...

Dr Xiao-Qi Zhou and colleagues at the University of Bristol's Centre for Quantum Photonics and the University of Queensland, Australia, have shown that controlled operations "” ones that are implemented on the condition that a "control bit" is in the state 1 "” can be dramatically simplified compared to the standard approach. The researchers believe their technique will find applications across quantum information technologies, including precision measurement, simulation of...
