(Phys.org) —Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. An important consequence of this inherent kinship is that measuring a property of A (say, the particle's polarization) is necessarily to know the corresponding property of B, even if you're not there with a detector to observe B and even if (as explained below) the existence of that property had no prior fixed value until the moment particle A was detected. http://phys.org/news288283333.html Physics Mon, 20 May 2013 15:42:22 EST news288283333 An Australian team led by researchers at the University of New South Wales has achieved a breakthrough in quantum science that brings the prospect of a network of ultra-powerful quantum computers - connected via a quantum internet –closer to reality. http://phys.org/news286625403.html Physics Wed, 01 May 2013 13:00:13 EST news286625403 Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience in our daily lives. http://phys.org/news281261681.html Physics Thu, 28 Feb 2013 08:14:57 EST news281261681 (Phys.org)—The Vienna research team led by Anton Zeilinger has achieved a new milestone in the history of quantum physics: The scientists were able to generate and measure the entanglement of the largest quantum numbers to date. To this end, the researchers developed a new method for entangling single photons which gyrate in opposite directions. This result is a first step towards entangling and twisting even macroscopic, spatially separated objects in two different directions. The researchers at the Vienna Center for Quantum Science and Technology (VCQ), situated at the University of Vienna, and the Institute for Quantum Optics and Quantum Information (IQOQI) at the Austrian Academy of Sciences have were able to get their pioneering results published in the current issue of the renowned scientific journal Science. http://phys.org/news271063126.html Physics Fri, 02 Nov 2012 08:19:09 EST news271063126 Vienna University of Technology physicists have studied the transition of quantum systems towards thermal equilibrium. They detected an astonishingly stable intermediate state between order and disorder. The results are being published in the journal Science. http://phys.org/news266148809.html Physics Thu, 06 Sep 2012 14:00:08 EST news266148809 (Phys.org)—Researchers from The Australian National University have taken a quantum leap towards developing the next-generation super-fast networks needed to drive future computing. http://phys.org/news265533420.html Physics Thu, 30 Aug 2012 08:17:09 EST news265533420 Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist. Their results will be published this week in the journal Nature Physics. http://phys.org/news254399591.html Physics Mon, 23 Apr 2012 11:33:23 EST news254399591 Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an experimental demonstration of quantum computation in which the input, the data processing, and the output remain unknown to the quantum computer. The international team of scientists will publish the results of the experiment, carried out at the Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna and the Institute for Quantum Optics and Quantum Information (IQOQI), in the forthcoming issue of Science. http://phys.org/news246202223.html Physics Thu, 19 Jan 2012 14:00:01 EST news246202223 (PhysOrg.com) -- Scientists at the Joint Quantum Institute (JQI) have for the first time engineered and detected the presence of high angular momentum collisions between atoms at temperatures close to absolute zero. Previous experiments with ultracold atoms featured essentially head-on collisions. The JQI experiment, by contrast, is able to create more complicated collisions between atoms using only lasers. This innovation may facilitate the creation of exotic quantum states that can be exploited for practical applications like quantum computing. The key to the JQI approach is to alter the atoms' environment with laser light. They "dress" rubidium atoms by bathing them in a pair of laser beams, which force the atoms to have one of three discrete values of momentum. In the JQI experiment, rubidium atoms comprise a Bose-Einstein condensate (BEC). BECs have been collided before. But the observation of high-angular-momentum scattering at such low energies is new. http://phys.org/news242573991.html Physics Thu, 08 Dec 2011 14:00:11 EST news242573991 The concepts of quantum technology promise to achieve more powerful information processing than is possible with even the best possible classical computers. To actually build efficient quantum computers remains a significant challenge in practice. A new scheme termed "coherent photon conversion", could potentially overcome all of the currently unresolved problems for optical implementations of quantum computing. The international team of scientists led by researchers from the University of Vienna introduces this new scheme this week in Nature. http://phys.org/news237729671.html Physics Thu, 13 Oct 2011 13:01:22 EST news237729671 Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large "macroscopic" object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales. A collaboration of scientists led by researchers from the Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna report this new scheme in the forthcoming issue of PNAS. http://phys.org/news235386902.html Physics Fri, 16 Sep 2011 10:15:24 EST news235386902 Researchers of the University of Vienna used a quantum mechanical system in the laboratory to simulate complex many-body systems.
