  • Free Space Quantum Key Distribution
    Publication number: 20230254135
    Abstract: A quantum key distribution system comprises: a transmitter (10) arranged to transmit a coded photon stream over a free space quantum channel (14), wherein the transmitter comprises a single photon source (30) arranged to generate a coded photon stream comprising photons representing QKD bit values, and attenuation means (32) arranged to attenuate the coded photon stream, the attenuation means being variable so as to provide a variable attenuation of the coded photon stream; a receiver (12) arranged to receive the coded photon stream from the quantum channel; and control means (34, 46) arranged to control the attenuation means so as to vary the attenuation.
