ABSTRACT An improved quantum key distribution test system operating at clock rates of up to 2GHz using a specially adapted commercially-available silicon single-photon counting module is presented. The use of an enhanced detector has improved the fiber-based quantum key distribution test system performance in terms of transmission distance and quantum bit error rate.

    ABSTRACT: We report a free-space quantum key distribution system designed for high-speed key transmission in urban areas. Clocking the system at gigahertz frequencies and efficiently filtering background enables higher secure key rates than those previously achieved by similar systems. The transmitter and receiver are located in two separate buildings 300 m apart in downtown Madrid and they exchange secure keys at rates up to 1 Mbps. The system operates in full bright daylight conditions with an average secure key rate of 0.5 Mbps and 24 h stability without human intervention.

    ABSTRACT: The afterpulse effect is one of the major bottlenecks limiting the performances of InGaAs/InP single-photon avalanche photodiodes (SPADs) for high-speed operation. In this paper, we present a practical and easy way to implement an afterpulse suppression scheme. Using an analog integrator circuit to discriminate small avalanche signals, we reduced drastically the afterpulse noise of the detector. At a repetition frequency of 25 MHz, the overall afterpulse probability is 1.48% with a detection efficiency of 15.6% and a dark count probability of 1.3× 10-5. In addition, the detector features a maximum count rate of 25 MHz.

    ABSTRACT: We demonstrate the first implementation of polarization encoding measurement-device-independent quantum key distribution (MDI-QKD), which is immune to all detector side-channel attacks. Active phase randomization of each individual pulse is implemented to protect against attacks on imperfect sources. By optimizing the parameters in the decoy state protocol, we show that it is feasible to implement polarization encoding MDI-QKD over large optical fiber distances. A 1600-bit secure key is generated between two parties separated by 10 km of telecom fibers. Our work suggests the possibility of building a MDI-QKD network, in which complicated and expensive detection system is placed in a central node and users connected to it can perform confidential communication by preparing polarization qubits with compact and low-cost equipment. Since MDI-QKD is highly compatible with the quantum network, our work brings the realization of quantum internet one step closer.
