A method for quantum communication between at least three receivers includes: The photons generated in step i) are generated in a signal wavelength range and an idler wavelength range that are spectrally separated from one another, and, in step ii), the photons are assigned to the quantum channels () such that, in step iii), only signal photons are transmitted to a first receiver () for the communication with all other receivers (), and, in step iii), only idler photons are transmitted to a second receiver () for the communication with all other receivers (), and, in step iii), both signal photons and idler photons are transmitted to the further receivers () for the communication with all other receivers (), and all receivers () are connected to the source () via in each case one quantum channel ().
