  • A NETWORK NODE, A TRANSMITTER AND A RECEIVER FOR QUANTUM KEY DISTRIBUTION OVER AN OPTICAL FIBER NETWORK
    Publication number: 20240056294
    Abstract: A network node configured to operate in an optical fiber network can comprise a quantum key distribution (QKD) communication unit adapted to communicate with another QKD communication unit of at least one other network node of the optical fiber network according to a CV-QKD mode and/or a DV-QKD mode. A control unit can be configured to control the QKD communication unit to operate in at least one of the CV-QKD mode and the DV-QKD mode. The control unit can be configured to switch operation of the QKD communication unit between the CV-QKD mode and the DV-QKD mode.
