Investigation of the Statistics of Single-Photon Counting by Two Photodetectors for Applications in Quantum Cryptography

A method for revealing a photon-number-splitting attack in quantum-cryptographic communication systems by measuring the photon-number distribution in a laser pulse is proposed. Instead of using a complex photon-numberresolving detector, we propose to use two conventional single-photon detectors based on avalanche photodiodes. The results of experiments on measuring the photon numbers in a laser pulse and their comparison with theoretical calculations are presented. The limits of the applicability of the proposed method are discussed.
