Latest Quantum information Stories
Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology (NIST) have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)—the first published error rate small enough to meet theoretical requirements for building viable quantum computers.
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 â€” ones that are implemented on the condition that a "control bit" is in the state 1 â€” can be dramatically simplified compared to the standard approach.
No-one likes a know-it-all but we expect to be able to catch them out: someone who acts like they know everything but doesn't can always be tripped up with a well-chosen question.
A general rule in data processing is that disturbances cause the distortion or deletion of information during data storage or transfer.
Tokyo, Jan 21, 2011 - (JCN Newswire) - Professor Kohei Itoh, who is developing quantum computers based on silicon semiconductors at Keio University's Faculty of Science and Technology, together with Dr.
Discovery moves quantum networks closer to reality.
Quantum information processing is arguably one of the most fascinating facets of modern quantum physics.
When confined to a 2-dimensional sheet, some exotic particle-like structures known as anyons appear to entwine in ways that could lead to robust quantum computing schemes.
An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers.
Any physical system - be it an electron, a molecule of water, a virus, a human being, a whole planet â€“ is characterized at each moment in time distinctively and specifically in a specific place by particular characteristics.
Open Systems & Information Dynamics (OSID) is journal published by World Scientific. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication,...
