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.

Long wavelength quantum cryptography and entanglement manipulations

Anders Karlsson, Mohamed Bourennane, Daniel Ljunggren +2 more

We will review ongoing work at KTH on quantum communication, discussing in particular two projects; long wavelength quantum cryptography, and entangled state manipulations. In order to extend quantum communications to longer distances it is essential to be able to use the low loss telecommunication window at 1550 nm. We, and recently others have for some time worked on quantum cryptography systems in this wavelength region. Much of the effort has been devoted to the investigation of the InGaAs avalanche photo diodes used as single-photon counters, and examples of the performances and systems implications will be given. As a second topic, for quantum communication beyond point-to-point transmission, it is of some interest to investigate the possibilities offered by multi-particle entangled states. Recently, very interesting results are emerging on purification using linear optics manipulations. We will discuss recent theory work on three-particle entangled states of the inequivalent GHZ-classes and the W-classes and the possibility to do entangled-state-assisted transformations between these classes, as well as to consider possible applications.

Long-distance stable “plug and play” quantum cryptography system

Chunyuan Zhou, Guang Wu, Xiuliang Chen +2 more

We have recently constructed a fiber-optic “plug and play” quantum cryptography system as shown in Fig.1, wherein a Faraday-Mirror was used to compensate the polarization mode dispersion and phase drifts. It worked at 1550 nm and was based on the B92 protocol[1]. We have achieved stable quantum key distribution in a standard telecom fiber with different working-distances of 10, 25 and 50 km, respectively, by using some specifically developed techniques to guarantee long-term stability of our system, such as polarization-independent phase-modulation for stable phase encoding and decoding, hybrid coincidence for efficient detection of single photons with coincidence-gated quenching of the single-photon detectors followed by coincident counting of the avalanche signals, and synchronized detection of single-photon pulses by coincidence counting gated with proper delay and width. These unique techniques greatly enhanced the fringe visibility of single-photon interference. And we have also demonstrated the application of our system in cryptographic communication by sending coded pictures from Alice to Bob using the sifted quantum keys.

Experimental long wavelength quantum cryptography: From single-photon transmission to key extraction protocols

Mohamed Bourennane, Daniel Ljunggren, Anders Karlsson +3 more

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.

Investigations on Long Wavelength Quantum Cryptography Systems

F. Gibson, Alexandru Hening, Mohamed Bourennane +4 more

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.
