Abstract

We present experiments on long wavelength (δ = 1.55 μm) ‘plug and play’ quantum cryptography systems. We discuss the performance of single-photon detectors at δ = 1.55 μm. Furthermore, we address the full implementation of the quantum cryptography protocol, discussing in detail the implementation of protocols for error correction and privacy amplification needed to get a secure key. We illustrate the theory with examples from a full software simulation to show the performance of the complete protocol in terms of final secure key creation rate.

Experiments on long wavelength (1550 nm) "plug and play" quantum cryptography systems

Mohamed Bourennane, F. Gibson, Alexandru Hening +5 more

Summary form only given. Quantum cryptography is a technique for establishing a fundamentally secure cryptographic key, using the encoding of the key on single photon pulses. In the recent years here has been a remarkable progress in experimental implementations at 1300 nm wavelength. However, for 1550 nm wavelength, there are few results, as the performance of single photon detectors for 1550 nm has been considered insufficient. We report on the implementation of a 1550 nm stable plug-and-play interferometric scheme for quantum cryptography, and for simplicity, we have only implemented a two-state encoding.

Investigations on Long Wavelength Quantum Cryptography Systems

Quantum cryptography is a technique for establishing a fundamentally secure key for cryptography using the encoding of the key on single photon states in such a way that an eavesdropper cannot acquire any information about the key without impairing detectable errors in the communication channel [1]. In the recent years there has been a remarkable progress in experimental implementations at 850 nm and 1300 nm wavelengths with secret key generation at kbits/s up to 48 km distance. However, for 1550 nm wavelength, where fiber losses are as smallest, progress has been hampered by the lack of good single photon detectors.

Quantum cryptography

V. L. Kurochkin, Igor G. Neizvestny

Work presents the brief review of the contemporary state of quantum cryptography science. Main principles of the quantum cryptography protocol development are illustrated by giving the example of BB84 protocol. Examples of experimental setups for the quantum key distribution through the atmosphere and fiber quantum channel are described in this work. The work presents results of experiments conducted on the developed setup based on single photon polarization coding. Problem of single photon detection in the visible and near IR area is considered. Work describes developed fiber based quantum cryptography working with the telecom wavelength 1555 nm. With the use of this experimental setup using the 25 km single mode telecom fiber (1555 nm wavelength) between sender and receiver we achieved the 450 bit/s quantum key generation with the use of 5 MHz pulse repetition rate, ~0.2 photon/pulse. Given the achieved photodetector parameters an average quantum bit error rate is less than 3.7%.

Quantum key distribution over distances as long as 30 km

C. Marand, Paul D. Townsend

We report the secure transmission of cryptographic keys over as long as 30 km of optical fiber, using an interferometric quantum cryptography scheme. Low error rates in the range 1.2–4% were obtained for the quantum transmissions, and error-free secret keys were distilled from the raw data by use of secure error-correction and privacy-amplification protocols.

Single-photon interference experiment over 100 km for quantum cryptography system using a balanced gated-mode photon detector

Hideo Kosaka, Akihisa Tomita, Yoshihiro Nambu +2 more

We demonstrate single-photon interference over 100 km using a balanced gated-mode photon detector and a plug & play system for quantum key distribution. The visibility with 0.1 photon/pulse was more than 80% after 100 km transmission. This corresponds to the fidelity of a quantum cryptography system of more than 90% and a QBER of less than 10%, satisfying the security criteria.
