QKD Over Long Distance; Crucial to Data Security. Quantum Key Distribution, QKD, utilizes photon entanglement to distribute encryption keys with near-total security. Research conducted
Japanese industry research and development teams have enabled a quantum key distribution (QKD) network over a distance of 7 kilometers with a speed over 10 Mbps.
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.
