University of Toronto quantum optics researchers Sajeev John and Xun Ma have discovered new behaviours of light within photonic crystals that could lead to faster optical information processing and compact computers that don't overheat. http://www.physorg.com/news180039909.html Physics Mon, 14 Dec 2009 19:05:46 EST news180039909 In an international first, scientists from the Institute of Quantum Optics and Quantum Information (IQOQI, Austria) produced a Bose-Einstein condensate of the alkaline-earth element strontium, thus narrowly winning an international competition between many first-rate scientific groups. Choosing the isotope 84Sr, which has received little attention so far, proved to be the right choice for the breakthrough. It can now be regarded as an ideal candidate for future experiments with atomic two-electron systems. http://www.physorg.com/news176994672.html Physics Mon, 09 Nov 2009 13:11:51 EST news176994672 (PhysOrg.com) -- By greatly amplifying one photon from an entangled photon pair, physicists have theoretically shown that human eyes can be used as detectors to observe quantum effects. Usually, detecting quantum phenomena requires sensitive photon detectors or similar technology, keeping the quantum world far removed from our everyday experience. By showing that it`s possible to perform quantum optics experiments with human eyes as detectors, the physicists can bring quantum phenomena closer to the macroscopic level and to everyday life. http://www.physorg.com/news173423784.html Physics Tue, 29 Sep 2009 09:10:03 EST news173423784 Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. In order to achieve control over single electrons in a bunch, ultrashort light pulses of a few femtoseconds duration are needed. http://www.physorg.com/news171031838.html Physics Tue, 01 Sep 2009 13:51:15 EST news171031838 (PhysOrg.com) -- Physicists at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna and Innsbruck, Austria, have created an interaction between light and a micromechanical resonator that is strong enough to transfer quantum effects. This is an important step towards quantum physics experiments in the macroscopic domain. They report about their result in the latest issue of the scientific journal Nature. http://www.physorg.com/news168771383.html Physics Thu, 06 Aug 2009 09:57:26 EST news168771383 (PhysOrg.com) -- In comparison to classical physics, quantum physics predicts that the properties of a quantum mechanical system depend on the measurement context, i.e. whether or not other system measurements are carried out. A team of physicists from Innsbruck, Austria, led by Christian Roos and Rainer Blatt, have for the first time proven in a comprehensive experiment that it is not possible to explain quantum phenomena in non-contextual terms. The scientists report on their findings in the current issue of Nature. http://www.physorg.com/news167461123.html Physics Wed, 22 Jul 2009 13:00:04 EST news167461123 A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the controlled-NOT quantum logic gate in optical fibres with high fidelity. http://www.physorg.com/news162736415.html Physics Thu, 28 May 2009 13:34:04 EST news162736415 (PhysOrg.com) -- In the online edition of Nature Physics, theoretical physicists from the Institute for Quantum Optics and Quantum Information (IQOQI) and the University of Innsbruck today are presenting a completely new way of preparing quantum states in many-body systems. This means that for the first time even excited many-body states can be created in a targeted fashion, an important step in the exploration of solid states. http://www.physorg.com/news140016498.html Physics Sun, 07 Sep 2008 14:28:18 EST news140016498 Astronomical instruments needed to answer crucial questions, such as the search for Earth-like planets or the way the Universe expands, have come a step closer with the first demonstration at the telescope of a new calibration system for precise spectrographs. The method uses a Nobel Prize-winning technology called a 'laser frequency comb', and is published in this week's issue of Science. http://www.physorg.com/news139755149.html Physics Thu, 04 Sep 2008 13:52:29 EST news139755149
