Abstract

We report on a quantum key distribution effected with a two-way deterministic protocol over a standard telecommunication fiber. Despite the common belief of a prohibitive loss rate for such a scheme, our results show its feasibility on distances of few tenths of kilometers.

Experimental demonstration of continuous-variable quantum key distribution over 80 km of standard telecom fiber

Paul Jouguet, Sébastien Kunz-Jacques, Anthony Leverrier +2 more

Continuous-variable quantum key distribution (CVQKD) [1] is a promising alternative to commonly used discrete-variable QKD protocols, because this technology can be implemented with standard telecom components and recent results suggest that it will be compatible with standard wavelength division multiplexed telecommunication networks [2]. Security proofs against general eavesdropping attacks are available for CVQKD protocols using Gaussian modulation [3], and field implementations over deployed telecommunication networks have been demonstrated over the past few years [4].

Entanglement-based quantum key distribution in standard telecom channels for long-distance multi- user network implementation

Djeylan Aktas, Bruno Fedrici, Laurent Labonté +1 more

Quantum Key distribution (QKD) enables two parties, Alice and Bob, to share a sequence of random bit whose secrecy is guaranteed by the fondations of quantum physics. The natural counterpart of this genuine inviolability lies in moderate key generation rates and achievable distances, due to severe exper- imental constraints, such as photon generation probabilities, detector's inefficiencies, detector's dark counts, and losses in fiber distribution channels. As well as improving these exper- imental resources since the last couple of years, several strate- gies are developed for increasing this bit rate. One promising way consists in exploiting the spectral correlations of time- energy entangled photons, enabling higher information con- tent per paired photon. Our idea is to combine the maturity of QKD schemes with high performance standard telecom com- ponents to propose a practical scheme allowing the distribu- tion of secret bits over 200 km at unprecedented rates.

Quantum cryptography, exclusively known as Quantum key distribution (QKD), has attracted a lot of attention in the recent years with the discovery that it can provide absolute secrecy for communications.We report a new architecture for constructing a fiber-based network of quantum key distribution using optical wavelength division multiplexing in the fiber, and also using some wavelength protocols.The advantages are discussed in detail for demonstrating the experimental report in the way of feasibility for the proposed architecture.

Distributing Polarization-Entangled Photon Pairs with High Rate Over Long Distances through Standard Telecommunication Fiber

Lijiong Shen, Chang Hoong Chow, Justin Yu Xiang Peh +3 more

Distributing entanglement through standard telecommunication fiber is particularly important for quantum key distribution protocols with low vulnerability over metropolitan distances. However, entanglement distribution over long distance through optical fiber so far could only be accomplished with moderate photon pair rates. In this work, we present entanglement distribution over 50 km of standard telecommunication fiber with a pair rate of more than 10 000 ${\mathrm{s}}^{\ensuremath{-}1}$ using a bright nondegenerate photon pair source. Signal and idler wavelengths of this source are optimized for low dispersion in optical fiber and high efficiency for single-photon avalanche diode detectors, respectively. The resulting modest hardware requirement and high rate of detected entangled photon pairs could significantly enhance practical entanglement-based quantum key distribution in existing metropolitan fiber networks.
