Vorrichtung und Verfahren für die Quantenkryptographie

摘要

The invention relates to a quantum cryptography system for the safe generation of keys, especially using signal sources and analytical channels. The signal sources are arranged spatially separately in such a way that the wave fronts of the light signals emitted by them are partially superimposed on the input of the quantum channel. The analytical channels are arranged in such a way that the wave front of the light signals exiting the quantum channel is spatially split up and at least two of the sections are analyzed in a quantum mechanical state.
