Abstract

Quantum key distribution is a new technique that permits secure distribution of a bit string, used as a key in cryptographic protocols. The present quantum‐cryptographic protocols use a single photon to carry information; hence, for the construction of an optical setup able to support quantum‐cryptographic protocols, it is necessary to use single‐photon detectors. In this paper, numerical simulations and experimental results of single‐photon detectors in 1550 nm, using avalanche photodiode, are shown. © 2003 Wiley Periodicals, Inc.
