Patent abstract
Systems and methods for verifying error-free transmission of the synchronization (“sync”) channel of a QKD system are disclosed. The method includes sending a first pseudo-random bit stream (PRBS) over the sync channel from Alice to Bob, and verifying at Bob the accurate transmission of the first PRBS. The method also includes sending a second pseudo-random bit stream (PRBS) over the sync channel from Bob to Alice, and verifying at Alice the accurate transmission of the first PRBS. If the transmissions of a select number of bits in the first and second PRBSs are error-free, then the sync channel is verified and the QKD system can commence operation.
