LLE Review, Volume 106 108 Practical quantum cryptography (QC) systems require ultrafast and high-quantum-efficiency (QE) single-photon detectors (SPD’s)1 with precise timing characteristics2 and sufficiently low dark counts. For fiber-optic QC systems, SPD’s working at the standard near-infrared (NIR) telecommunication wavelengths, namely 1.3 nm and/or 1.55 nm, with counting rates well above 1...
متن کاملHigh Speed Travelling Wave Single-Photon Detectors With Near- Unity Quantum Efficiency
Ultrafast, high quantum efficiency single photon detectors are among the most sought-after elements in modern quantum optics and quantum communication. Close-to-unity photon detection efficiency is essential for scalable measurement-based quantum computation, quantum key distribution, and loophole-free Bell experiments. However, imperfect modal matching and finite photon absorption rates have u...
متن کاملHigh-efficiency single-photon detectors.
Visible light photon counters (VLPCs) and solid-state photomultipliers (SSPMs) are high-efficiency single-photon detectors which have multi-photon counting capability. While both the VLPCs and the SSPMs have inferred internal quantum efficiencies above 93%, the actual measured values for both the detectors were in fact limited to less than 88%, attributed to in-coupling losses. We are currently...

LLE Review, Volume 115 153 Introduction Fast and reliable single-photon detectors (SPD’s) have become a highly sought after technology in recent years.1 Some of the most interesting applications for SPD’s, which include quantum communications and quantum key distribution,2 as well as satellite communications, require devices that can successfully operate at telecommunication wavelengths, namely...
متن کاملHigh-speed and high-efficiency travelling wave single-photon detectors embedded in nanophotonic circuits
Ultrafast, high-efficiency single-photon detectors are among the most sought-after elements in modern quantum optics and quantum communication. However, imperfect modal matching and finite photon absorption rates have usually limited their maximum attainable detection efficiency. Here we demonstrate superconducting nanowire detectors atop nanophotonic waveguides, which enable a drastic increase...
