"Toshiba Has a Plan to Extend Quantum Security to Record-Breaking Distances"

Toshiba has devised a new method in which secure encrypted messages are transmitted through the use of quantum mechanics. The method is expected to use fiber optic cables to send quantum keys between the sender and recipient up to 550 kilometers apart. This article continues to discuss the method proposed by researchers at Toshiba, other similar methods, and potential uses of quantum key distribution in the future.
