Quantum key distribution at 1550nm with twin superconducting single-photon detectors

Robert H. Hadfield, Jonathan L. Habif, J. Schlafer +2 more

The authors report on the full implementation of a superconducting detector technology in a fiber-based quantum key distribution (QKD) link. Nanowire-based superconducting single-photon detectors (SSPDs) offer infrared single-photon detection with low dark counts, low jitter, and short recovery times. These detectors are highly promising candidates for future high key rate QKD links operating at 1550nm. The authors use twin SSPDs to perform the BB84 protocol in a 1550nm fiber-based QKD link clocked at 3.3MHz. They exchange secure key over a distance of 42.5km in telecom fiber and demonstrate that secure key can be transmitted over a total link loss exceeding 12dB.

Performance of various quantum-key-distribution systems using 1550nm up-conversion single-photon detectors

Jiao Rongzhen, Feng Chen-Xu, Wenhan Zhang +3 more

We compare the performance of various quantum-key-distribution (QKD) systems using 1550nm up-conversion single-photon detectors. The analysis is based on the error rate and the secure communication rate as a function of distance for three QKD protocols: the Bennett-Brassard 1984, the Beruiett-Brassard-Vlerinin 1992, and the coherent differential-phase-shift keying (DPSK) protocols. We discussed that the security of DPSK protocol against any type of individual photon splitting attack and concluded that the simple and efficient DPSK protocol allows for more than 200km of secure communication distance with high communication rates.

Single‐photon detectors for quantum key distribution in 1550 nm: Simulations and experimental results

Rubens Viana Ramos, George A. P. Thé

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.
