Abstract
There is herein disclosed a system for performing Quantum Key Distribution, the system including a transmitter adapted to transmit a plurality of optical pulses, a first receiver, a second receiver, an optical switch with an input which is in optical communication with the transmitter, the switch being switchable between a first switching position in which the input is optically connected to the first receiver, and a second switching position in which the input is optically connected to the second receiver, the system further including a guide for guiding a portion of the plurality of optical pulses to the first receiver via an optical path that bypasses the optical switch.
