CESNET successfully transmits precise time and frequency in parallel with quantum keys

CESNET announced the successful cross-border transmission of very precise time and frequency, which is being implemented on the link between Ostrava and Těšín in Poland in parallel with testing of encrypted communication using quantum key distribution (QKD). This first national, but also international intercity QKD transmission, which was carried out on the territory of the Czech Republic, was launched in July last year. Two members of the e-INFRA CZ consortium – CESNET and the national supercomputing centre IT4Innovations – and the Polish academic network PSNC are collaborating on the project.
