Abstract
A method for Quantum Communication, including the steps: obtaining, by a detector, a base signal, wherein the base signal includes an indication of a background optical noise of a communication channel; determining, based on the obtained base signal, a width of a time gate value; applying to the detector the determined width of time gate; and obtaining a QKD signal including QKD signal pulses sent through the communication channel by applying the time gate having the determined width for filtering the background optical noise. A corresponding optical receiver, QKD pulse stream and QKD system for quantum communication are also provided.
