Scientists create first quantum router, but don't throw your 802.11ac out yet


A common vision of the future has us with our feet up, while robots do all the work. Another one sees the end of silicon, with quantum computers doing all the heavy lifting. That second prophecy inches just a smidgen closer with the news of the world's first quantum router. Developed at Tsinghau University in China, the router makes a quantum photon from two separate photons in different polarized states. At this point, things start to get a little, well, mind-bending, as they are wont to do in the quantum world. The net result, however, is one qubit of data being "routed" at a time. While this won't be powering any serious networks anytime soon, the all important proof of concept is there, and we imagine, in a parallel universe simultaneously.
