摘要： 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.

摘要： A signal transmitter and a signal receiver for interpreting a received message are provided. The receiver is configured to perform the steps of: decoding a first part of the message using a channel decoding scheme with a predefined set of decoding parameters to form a first data block; and subsequently decoding a second part of the message using the channel decoding scheme with decoding parameters that are at least partially dependent on the content of the first data block.

摘要： A continuous variable quantum key distribution system comprises a transmitter and a receiver. The first quantum signal has a first polarization and is associated with first quadrature components and the second quantum signal has a second polarization and is associated with second quadrature components. The receiver receives the quantum signals transmitted by the transmitter via a quantum communication channel; estimates a channel matrix representing the polarization rotation of the first and second polarization caused by the quantum communication channel; modifies the received first and second quantum signals on the basis of the polarization rotation; and uses the modified received first and second quantum signals for generating a secret key. The transmitter may modify the transmitted first quantum signal and the transmitted second quantum signal based on the polarization rotation and use the modified transmitted first quantum signal and the modified transmitted second quantum signal for generating a secret key.
