InGaAs/InP single-photon detectors with 60% detection efficiency at 1550 nm. [PDF]
Review of Scientific Instruments, 2020 InGaAs/InP single-photon detectors (SPDs) are widely used for near-infrared photon counting in practical applications. Photon detection efficiency (PDE) is one of the most important parameters for SPD characterization, and therefore, increasing PDE ...

Security of quantum key distribution with detection-efficiency mismatch in the multiphoton case [PDF]
Quantum, 2020 Detection-efficiency mismatch is a common problem in practical quantum key distribution (QKD) systems. Current security proofs of QKD with detection-efficiency mismatch rely either on the assumption of the single-photon light source on the sender side or

SmartTrack: efficient predictive race detection [PDF]
Proceedings of the 41st ACM SIGPLAN Conference on Programming Language Design and Implementation, 2020 Widely used data race detectors, including the state-of-the-art FastTrack algorithm, incur performance costs that are acceptable for regular in-house testing, but miss races detectable from the analyzed execution. Predictive analyses detect more data races in an analyzed execution than FastTrack detects, but at significantly higher performance cost ...

BELL'S INEQUALITIES DETECT EFFICIENT ENTANGLEMENT [PDF]
International Journal of Quantum Information, 2004 We review the status of Bell's inequalities in quantum information, stressing mainly the links with quantum key distribution and distillation of entanglement. We also prove that for all the eavesdropping attacks using one qubit, and for a family of attacks of two qubits, acting on half of a maximally entangled state of two qubits, the violation of a ...

Security proof of practical quantum key distribution with detection-efficiency mismatch [PDF]
, 2020 Quantum key distribution (QKD) protocols with threshold detectors are driving high-performance QKD demonstrations. The corresponding security proofs usually assume that all physical detectors have the same detection efficiency.

A mathematical model of semiconductor detector gamma-efficiency calibration for rectangular cuboid (brick-shape) sources [PDF]
Nuclear Technology and Radiation Protection, 2018 Rectangular cuboid (rectangular parallelepiped), i. e., brick-shape sources are not really common in general gamma-spectrometry practice with semiconductor detectors, where axially symmetrical sources prevail.
