(PhysOrg.com) -- Two Dartmouth researchers have found a way to develop more robust `quantum gates,` which are the elementary building blocks of quantum circuits. Quantum circuits, someday, will be used to operate quantum computers, super powerful computers that have the potential to perform extremely complex algorithms quickly and efficiently. http://www.physorg.com/news156101597.html Physics Thu, 12 Mar 2009 18:33:49 EST news156101597 (PhysOrg.com) -- "For certain tasks, quantum computers are more powerful than their classical counterparts. The task to be performed is the same for quantum or classical systems. However, the former ones can do it in a more efficient way," David Gross tells PhysOrg.com. "But we can`t pinpoint the exact reason why a quantum computer is more powerful. Until now, it has been accepted that the reason is entanglement. But entanglement is the easy answer, and we have discovered that it is not so simple." http://www.physorg.com/news162468404.html Physics Mon, 25 May 2009 11:07:15 EST news162468404 (PhysOrg.com) -- It is a truth universally acknowledged that quantum computing must have entanglement. http://www.physorg.com/news147698804.html Physics Fri, 05 Dec 2008 11:26:44 EST news147698804 (PhysOrg.com) -- `Right now, classical computers are faster than quantum computers,` René Stock tells PhysOrg.com. `The goal of quantum computing is to eventually speed up the time scale of solving certain important problems, such as factoring and data search, so that quantum computing can not only compete with, but far outperform, classical computing on large scale problems. One of the most promising ways to possibly do this is with ion traps.` http://www.physorg.com/news161348276.html Physics Tue, 12 May 2009 11:58:24 EST news161348276 (PhysOrg.com) -- Physicists from The University of Queensland have found the emerging field of quantum computing may be more stable than previously thought. http://www.physorg.com/news168706585.html Physics Wed, 05 Aug 2009 16:50:01 EST news168706585 Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. The work is published online today on the Science Express Web site. http://www.physorg.com/news177938057.html Physics Fri, 20 Nov 2009 11:18:55 EST news177938057 The first desktop computers changed the way we managed data forever. Three decades after their introduction, we rely on them to manage our time, social life and finances -- and to keep this information safe from prying eyes and online predators. http://www.physorg.com/news168179517.html Technology Thu, 30 Jul 2009 13:32:29 EST news168179517 A huge consortium of European researchers is solving some of the fundamental obstacles blocking real quantum computing applications in the short term. At the same time, it is helping to pave the way to a quantum computer. http://www.physorg.com/news163995787.html Nanotechnology Fri, 12 Jun 2009 08:30:02 EST news163995787 Air Force Office of Scientific Research(AFOSR)-supported physicists at the University of Michigan are developing innovative components for quantum, or super-fast, computers that will improve security for data storage and transmission. http://www.physorg.com/news171731312.html Physics Wed, 09 Sep 2009 16:20:02 EST news171731312 Quantum physics is both mysterious and difficult to grasp. Barry Sanders, director of the University of Calgary's Institute for Quantum Information Science, is hoping to change that. http://www.physorg.com/news148740939.html Physics Wed, 17 Dec 2008 12:55:39 EST news148740939 (PhysOrg.com) -- Complex computer encryption codes could be solved and new drug design developed significantly faster thanks to new research carried out by the University of Surrey. http://www.physorg.com/news137251532.html Physics Wed, 06 Aug 2008 14:25:32 EST news137251532 One of the most exciting and diverse fields of science today involves quantum information processing. There are many designs for quantum computers suggested, and a few that have been demonstrated. Among the demonstrated suggestions for a quantum computer is a one-way quantum computation process that makes use of a two-photon four-qubit cluster state. http://www.physorg.com/news110454259.html Physics Mon, 01 Oct 2007 10:44:19 EST news110454259 Researchers at UC Santa Barbara have recently demonstrated a breakthrough in the quantum control of photons, the energy quanta of light. This is a significant result in quantum computation, and could eventually have implications in banking, drug design, and other applications. http://www.physorg.com/news162814379.html Physics Fri, 29 May 2009 11:13:27 EST news162814379 (PhysOrg.com) -- Quantum entanglement, a type of correlation peculiar to quantum objects, has been found to disregard completely the "half-life" rule that is obeyed by all natural processes, such a radioactive decay. http://www.physorg.com/news152899335.html Physics Tue, 03 Feb 2009 16:02:40 EST news152899335 The world`s shortest light pulse containing just one photon has been produced by Oxford University scientists. http://www.physorg.com/news127049722.html Physics Thu, 10 Apr 2008 12:35:22 EST news127049722
