‘Untappable’ encryption edges closer after quantum messaging breakthrough
Researchers at Toshiba Europe have used quantum key distribution (QKD) cryptography to send messages a record 254km using a traditional fibre optic cable network. It’s the first time scientists have achieved a coherent quantum communication using existing telecomms infrastructure. The breakthrough marks a step closer to ultra-secure quantum encryption, which could fend off hacks from even the most advanced classical and quantum computers of the future. QKD is a form of communication that uses the principles of quantum mechanics to securely share encryption keys between two parties. It transmits information in the form of light. These photons carry qubits, the…This story continues at The Next Web [...]
