Toshiba's Quantum Information Group, based in Cambridge, UK, has been actively involved in quantum technology R&D for over 20 years. Their significant achievements in this field include the first demonstration of QKD over 100km of fibre, the first continuous operation of one-way QKD, the first demonstration of fibre-based QKD using a true single-photon source, the first demonstration of a secure bit rate exceeding 1 Mbit/sec, the first upstream quantum access network, record distances and bit rates for QKD/data multiplexing, the first demonstration of quantum-secured WDM transmission through a single installed fibre and the first proposal and demonstration of Twin Field QKD.
