Abstract: A quantum key distribution protocol for optical fiber systems that does not require the adjustment of the receiving optical system has been proposed. It significantly simplifies the practical implementation of the system and ensures stable operation even at the imbalance of the receiving optical system. The robustness of the protocol has been explicitly proven taking into account side channels of information leakage.
