The Hub is introducing a new QKD approach into its portfolio with CV-QKD, based on continuous quantum light signals. The aim is experimental development of robust, high-rate CV-QKD systems for secure communication in fibre, free-space and satellite links . Advanced quantum encoding and data processing techniques are being developed and incorporated in order to greatly improve the practical robustness of these new systems. A further goal is the experimental development of CV-QKD with squeezed states, aiming to fully exploit the security advantages of continuous variable entanglement in quantum communications.
