Researchers at the Cavendish Laboratory in Cambridge and Toshiba Research Europe have produced a new way to produce entangled photons, a key technique for quantum encryption and computing.

"This is a real breakthrough," lead researcher Andrew Shields told ZDNet UK on Wednesday. "This is a voltage-powered LED, not a large, cumbersome system. It's cheaper and much more robust. We can see many of these being built into a single chip for quantum computing."
