Toshiba shrinks quantum key distribution onto a chip

 Researchers at Toshiba Europe have developed the world’s first chip-based quantum key distribution (QKD) system, potentially paving the way for much more secure networks.QKD systems typically comprise a complex fibre-optic circuit, integrating discrete components, such as lasers, electro-optic modulators, beam-splitters and fibre couplers. This project aimed to develop a QKD system on a single chip. Random bits for preparing and measuring the...
