1. An optically-based digital-to-analogue converter comprising:
a first pulse shaper and a second pulse shaper;
a first combiner comprising a first input for an optical signal from the first pulse shaper, and a second input for a further optical signal;
a second combiner comprising a first input for an optical signal from the second pulse shaper, and a second input for the further optical signal;
a first quantum pulse shaper and a second quantum pulse shaper, wherein the first quantum pulse shaper receives an output signal of the first combiner, and the second quantum pulse shaper receives an output signal of the second combiner;
a third combiner to combine output signals of the first quantum pulse shaper and the second quantum pulse shaper; and
a detector to detect an output signal of the third combiner.
