(Phys.org)—Researchers from Toshiba and Cambridge University working together in Britain have developed a technique for sending quantum encryption keys over a shared fiber cable. As they describe in their paper published in Physics Review X, their technique involves employing a super sensitive photon detector capable of detecting the photons that make up a quantum key at the precise moment they arrive.
