Abstract
Twin-field quantum key distribution on optical fibers, a promising approach to long-distance secure communication, can take advantage from atomic clocks technologies such as narrow linewidth lasers and phase-coherent distribution of optical pulses. We will describe the integration of these technologies in a TF-QKD setup implemented on an ex-tended metropolitan fiber network and report on the expected QKD performances.
