Zusammenfassung:It is claimed a system (1) for polarization compensation, preferably for quantum communication, quantum information and quantum cryptography, comprising a source (2) generating polarized photons in at least two non-orthogonal polarization states, and a first receiver with a detection means (3), whereby the detection means (3) enables the polarization measurement of the photons in the at least two non-orthogonal polarization bases, and a first quantum channel (4), for guidance of the polarized photons from the source (2) to the first receiver, and a polarization compensation means (6) arranged in the first quantum channel (4). According to the invention, the polarization compensation means (6) comprises five wave-plates, whereby three wave-plates are rotatable.
