Abstract
A method () of quantum communication, the method comprising steps of: receiving () data for encrypted transmission on an optical channel; determining () a fill level of a key buffer storing shared secret key bits distributed by a quantum key distribution, QKD, system via the optical channel; determining () a bandwidth and an encryption technique for encrypted transmission of the data dependent on the determined fill level; encrypting () the data using the determined encryption technique; transmitting () the encrypted data at the determined bandwidth on the optical channel; determining () a quantum key generation rate required to support ongoing encrypted transmission of data on the optical channel at the determined bandwidth and encryption technique; and configuring () the QKD system to perform quantum key generation at the determined quantum key generation rate. Quantum communication apparatus configured to implement the method.
