+ - Major Quantum Information Technology Breakthroughs

There have been commercial quantum encryption devices on the market for quite some time now, but these have been limited to point to point connections. Having a protocol that allows the seamless integration of quantum cryptography into the existing network stack raises this to an entirely different level.

Just days after this news came the announcement that the company D-Wave, that claims to ship the first quantum computing device, aced a test when their machine was put into direct comparison with conventional hardware. It wasn't even close. For the class of problems that the D-Wave machine is designed for, the next best algorithm on a regular CPU performed several thousand times worse."
