Abstract
The invention relates to a IM bias voltage determining method adapted to determine an IM bias voltage corresponding to a desired Quantum Bit Error Rate based on the following formula Q ( V IM ) = Q 0 + R err R err + R cor where Q(VIM) is the QBER dependent of the IM bias voltage VIM, Q0 is the optimal minimal QBER, Rerr is the number of erroneous detections, Rcor is the number of correct detections and VIM is the IM bias voltage.
