That ability would disrupt the absolute security of quantum encryption, theoretical physicist Todd Brun and collaborators report online in the quantum physics archive.</p> http://www.gyre.org/news/take-time-break-quantum-encryption#comments Cryptography Quantum Cryptography Time Travel Fri, 14 Nov 2008 13:09:49 -0800 Greg Schnippel 5325 at http://www.gyre.org http://www.gyre.org/news/nsa-and-army-quest-quantum-physics-jackpot <p>The US Army Research Office and the National Security Agency (NSA) are together looking for some answers to their quantum physics questions on quantum computing and cryptography.</p> http://www.gyre.org/news/nsa-and-army-quest-quantum-physics-jackpot#comments Metacomputing Physics Quantum Computing Quantum Cryptography Wed, 29 Oct 2008 07:17:15 -0700 Greg Schnippel 5274 at http://www.gyre.org http://www.gyre.org/news/unbreakable-encryption-unveiled <p>Perfect secrecy has come a step closer with the launch of the world's first computer network protected by unbreakable quantum encryption at a scientific conference in Vienna.</p> <p>The network connects six locations across Vienna and in the nearby town of St Poelten, using 200 km of standard commercial fibre optic cables.</p> <p>Quantum cryptography is completely different from the kinds of security schemes used on computer networks today.</p> <p><a href="http://www.gyre.org/news/unbreakable-encryption-unveiled">read more</a></p> http://www.gyre.org/news/unbreakable-encryption-unveiled#comments Cryptography Quantum Cryptography Wed, 29 Oct 2008 12:31:54 -0700 Greg Schnippel 5277 at http://www.gyre.org http://www.gyre.org/news/quantum-encryption-verge-commercial-use <p>A group of international researchers and Siemens Austria has demonstrated in Vienna the transmission of quantum-encrypted messages across commercial telecommunication links.
