Abstract

Differential-phase-shift quantum key distribution (DPS-QKD) with an extended degree of freedom of measurement is proposed. Extending the degree of freedom makes it possible to strengthen the DPS-QKD scheme against intercept-and-resend attacks. The feasibility of this idea is experimentally demonstrated.
