A device and a method for synchronizing entanglement sources with optical pump in a quantum communication network are disclosed. The device includes a pulsed optical source allowing emission of telecom wavelength optical clock pulses distributed in parallel to the entanglement sources to ensure synchronization of the entanglement sources; and for each of the entanglement sources, a frequency conversion device, allowing frequency conversion of the distributed telecom wavelength optical clock pulses to a wavelength adapted to optically pump the entanglement source. The method includes emitting and distributing in parallel, to the entanglement sources, telecom wavelength optical clock pulses; and locally, at each of the entanglement sources, frequency converting the telecom wavelength optical clock pulses to a wavelength adapted to optically pump the entanglement source.
