    "abstract": "We investigate limitations imposed by sequential attacks on the performance\nof differential-phase-shift quantum key distribution protocols that use pulsed\ncoherent light. In particular, we analyze two sequential attacks based on\nunambiguous state discrimination and minimum error discrimination,\nrespectively, of the signal states emitted by the source. Sequential attacks\nrepresent a special type of intercept-resend attacks and, therefore, they do\nnot allow the distribution of a secret key.",
