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 where Q(V) is the QBER dependent of the IM bias voltage V, Qis the optimal minimal QBER, Ris the number of erroneous detections, Ris the number of correct detections and Vis the IM bias voltage.
