  • Transmitter and receiver for transmitting and receiving a quantum key
    Patent number: 11343086
    Abstract: A transmitter provides an optical signal for transmitting a quantum key over a network. The transmitter comprises a first generator configured to generate a quantum signal, the quantum signal comprising a sequence of frames. The transmitter comprises a second generator configured to generate a pilot signal. The pilot signal comprises a sequence of signatures that is in synchrony with the sequence of frames. The transmitter comprises an optical modulator configured to generate the optical signal by modulating an optical carrier based on the quantum signal and the pilot signal. A corresponding receiver is proposed for receiving the optical signal and for extracting the quantum key.
