Quantum Key Distribution Takes a Sizeable Step
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.
