BT and Toshiba have announced plans to build the world’s first commercially available, quantum-secured metro network in London. The network will connect sites in London’s West End, the City and the M4 corridor, providing data services secured using quantum key distribution (QKD) and post-quantum cryptography (PQC) encryption.
Toshiba breaks quantum communication record with 600 km of optical fibers TOSHIBA ANNOUNCES BREAKTHROUGH IN LONG DISTANCE QUANTUM COMMUNICATION -New dual band stabilisation technique cancels
The Austrian Institute of Technology joins the European Space Agency and global satellite operator SES in a venture to secure communications. Using quantum key distribution techniques, the goal is to enable quantum encryption key distribution via satellite. QKD via satellite overcomes the degradation of data over distance and, more importantly, provides a nearly unbreakable delivery of cryptographic keys.
Twin-field quantum key distribution (TF-QKD) has been publicly announced by a team of scientists from Toshiba Research in the U.K. Seeking to extend the range of QKDs with an improvement in bandwidth. Simply, a quantum repeater is placed between two communicating parties. Both parties send their code to the repeater which then relays measurements of the entangled signals.
