Transmitter for a quantum communication system, a quantum communication system and a method of generating intensity modulated photon pulses

摘要

A transmitter for a quantum communication system, comprising:a photon source unit comprising a photon source;a first intensity modulator, configured to receive an input light pulse from the photon source unit, the first intensity modulator comprising: a first element, configured to split the input light pulse into two components;a phase modulator, configured to apply a phase shift between the two components; anda second element, configured to interfere the two components;wherein at least one of the first element and the second element is asymmetric.
