| Abstract: | The analysis is based on the error rate and the secure communication
rate as functions of distance for three quantum-key-distribution
(QKD) protocols: the Bennett--Brassard 1984, the
Bennett--Brassard--Mermin 1992, and the coherent
differential-phase-shift keying (DPSK) protocols. We consider the
secure communication rate of the DPSK protocol against an arbitrary
individual attack, including the most commonly considered
intercept-resend and photon-number splitting attacks, and concluded
that the simple and efficient differential-phase-shift-keying
protocol allows for more than 200 km of secure communication
distance with high communication rates. |
