Abstract: Some embodiments relate to a QKD transmitter configured to generate a plurality of pulse signals, wherein voltage polarity of at least one of the plurality of pulse signals is opposite to a voltage polarity of at least another one of said plurality of pulse signals, combine the plurality of pulse signals and generate therefrom a light-modulating signal, modulate light signals by the light-modulating signal, measure the modulated light signals and generate measurement data indicative thereof, and adjust at least one of amplitude and delay time of at least some of the plurality of pulse signals for transmission of a desired quantum communication state.
