摘要： A QKD arrangement with a photon source generating entangled idler and signal photons, with two measuring units, one of which receiving the idler photons and the other one receiving the signal photons, and each including an optical module with photon channels, wherein a photon passes a photon channel as a function of its polarization, and a device for detecting the photons in association to its respective photon channel, as well as a time control for timingly adjusting the detection devices; the photon source is adapted for pulsed emission of photon pairs, and an interrupting unit supplying the signal photons to the optical module in pulsed manner is arranged upstream of the other measuring unit, the photon channels in each optical module including delay units with different delay periods, and only one single-photon detector associates the photons to the photon channels on the basis of a time pattern.
