“…One can currently expect to exchange up to 1 Mbits of secret key per second, over a point-to-point QKD link of 20 km [62]. The maximum span of QKD links is now roughly around 100 km or even 140 km [62,63] (depending on the type of single photon detector that is used) at 1550 nm on a telecom dark fiber. A comparable maximum span has also been reached in the context of ground-to-ground free space QKD [64].…”

“…at the notable exception of photodetectors. Photodetection is currently the bottleneck for the performance of QKD systems, but it is important to keep in mind that, even on that side, although there are many technical problems to overcome, there are very few fundamental limitations for rate and distance, as detection methods are making significant progresses [65,66,58,62,63,60]. Another approach, known as "continuous variables QKD" (CVQKD) uses only standard PIN photodiodes, but requires more sophisticated data postprocessing in order to extract the secret keys [67].…”

The appealing feature of quantum key distribution (QKD), from a cryptographic viewpoint, is the ability to prove the information-theoretic security (ITS) of the established keys. As a key establishment primitive, QKD however does not provide a standalone security service in its own: the secret keys established by QKD are in general then used by a subsequent cryptographic applications for which the requirements, the context of use and the security properties can vary. It is therefore important, in the perspective of integrating QKD in security infrastructures, to analyze how QKD can be combined with other cryptographic primitives.The purpose of this survey article, which is mostly centered on European research results, is to contribute to such an analysis. We first review and compare the properties of the existing key establishment techniques, QKD being one of them. We then study more specifically two generic scenarios related to the practical use of QKD in cryptographic infrastructures: 1) using QKD as a key renewal technique for a symmetric cipher over a point-to-point link ; 2) using QKD in a network containing many users with the objective of offering any-to-any key establishment service. We discuss the constraints as well as the potential interest of using QKD in these contexts. We finally give an overview of challenges relative to the development of QKD technology that also constitute potential avenues for cryptographic research.

“…The achievement of high-SDE single-photon detectors has a broad impact on various research fields using telecommunication-wavelength photons such as quantum information, quantum optics, and optical communication because the conventionally used indium gallium ar- senide (InGaAs) avalanche photodiode (APD) has an SDE as low as ∼10% [7]. Recently, SSPDs have also been developed for shorter wavelength photons including those in the visible region.…”

SUMMARYIn this review, we present recent advances relating to superconducting nanowire single-photon detectors (SSPDs or SNSPDs) and their broad range of applications. During a period exceeding ten years, the system performance of SSPDs has been drastically improved, and lately excellent detection efficiencies have been realized in practical systems for a wide range of target photon wavelengths. Owing to their advantages such as high system detection efficiency, low dark count rate, and excellent timing jitter, SSPDs have found application in various research fields such as quantum information, quantum optics, optical communication, and also in the life sciences. We summarize the photon detection principle and the current performance status of practical SSPD systems. In addition, we introduce application examples in which SSPDs have been applied.

“…Sin embargo, todos estos protocolos presentan una carencia importante: sus tasas binarias (del orden de los pocos Mbps a distancias de 100 km) mediante el canal cuántico son bajas comparadas con las tasas de binarias mediante canal clásico (del orden de Gbps o Tbps a distancias de 100 km) [5][6][7][8]. Esto ha llevado a centrar la atención de varios investigadores con el fin aumentar las tasas binarias de los protocolos de distribución de clave cuántica (QKD) de forma que se equipare la generación y distribución de claves con la generación y distribución de información, logrando así, sistemas de comunicaciones más rápido y seguros.…”

Amplification of the bit rate for quantum key distribution based on cryptographic hash functions ABSTRACT:The security is a research area in a continuous evolving field and represents one of the most important perspective future lines in telecommunications. This work is focused on new techniques and methods employing the properties of quantum physics with the aim of obtaining unconditional security. Currently, these techniques and methods lack a key rate close to the current transmission rate. In order to improve the quantum key transmission rate, this article proposes the use of cryptographic hash functions used in the privacy amplification layer to expand the bit rate relying on the properties of these functions.
