SYSTEM FOR INTEGRATION OF CHANNELS WITH QUANTUM INFORMATION IN COMMUNICATION NETWORKS

摘要

System for integration of channels with quantum information in communication networks. The network includes fibre-optic segments (3) and conventional equipment (1, 2, 4), whilst a quantum key distribution (QKD) system has devices for the exchange of information by means of a quantum channel (7, 8). The system comprises at least one filter (6) for each one of said exchange devices (7, 8) and at least one unit for managing conventional and quantum channels (5) that reduces the noise in quantum channels and has at least the following functions: attenuation of insertion power of conventional channels in the network; different polarizations in the various conventional and quantum channels; and changes of wavelength assignment in not only conventional but also quantum channels.
