High-Speed Single-Photon Detection Using 2-GHz Sinusoidally Gated InGaAs/InP Avalanche Photodiode
We report a telecom-band single-photon detector for highspeed quantum key distribution systems. The single-photon detector is based on a sinusoidally gated InGaAs/InP avalanche photodiode. The gate repetition frequency of the single-photon detector reached 2 GHz. A quantum efficiency of 10.5 % at 1550 nm was obtained with a dark count probability per gate of 6.1×10−7 and an afterpulsing probabi...
متن کاملEfficient and low-noise single-photon avalanche photodiode for 1.244-GHz clocked quantum key distribution.
An efficient and low-noise 1.244-GHz gating InGaAs single-photon avalanche photodiode (SAPD) was developed for a high-speed quantum key distribution (QKD) system. An afterpulsing probability of 0.61% and a dark count probability per gate of 0.71 ×10-6 were obtained at a detection efficiency of 10.9% for 1.55-µm photons. Furthermore, our SAPD successfully coped with high detection efficiency (≤ ...
متن کامل100 km differential phase shift quantum key distribution experiment with low jitter up-conversion detectors.
We present a quantum key distribution experiment in which keys that were secure against all individual eavesdropping attacks allowed by quantum mechanics were distributed over 100 km of optical fiber. We implemented the differential phase shift quantum key distribution protocol and used low timing jitter 1.55 microm single-photon detectors based on frequency up-conversion in periodically poled ...
متن کاملMeasurement-device-independent quantum key distribution over 200 km.
Measurement-device-independent quantum key distribution (MDIQKD) protocol is immune to all attacks on detection and guarantees the information-theoretical security even with imperfect single-photon detectors. Recently, several proof-of-principle demonstrations of MDIQKD have been achieved. Those experiments, although novel, are implemented through limited distance with a key rate less than 0.1 ...
متن کاملLow-Noise Silicon Avalanche Photodiodes Fabricated in Conventional CMOS Technologies
We present a simple design technique that allows the fabrication of UV/blueselective avalanche photodiodes in a conventional CMOS process. The photodiodes are fabricated in a twin tub 0.8 m CMOS technology. An efficient guard-ring structure is created using the lateral diffusion of two n-well regions separated by a gap of 0.6 m. When operated at a multiplication gain of 20, our photodiodes achi...
