Experimental high-dimensional two-photon entanglement and violations of generalized Bell inequalities
Bell’s theorem experiments, which test the completeness of quantum mechanics, have a number of loopholes. However, one type—detection loopholes—becomes smaller when the measurement has more possibleExpand
Long-range time-of-flight scanning sensor based on high-speed time-correlated single-photon counting.
We describe a scanning time-of-flight system which uses the time-correlated single-photon counting technique to produce three-dimensional depth images of distant, noncooperative surfaces when theseExpand
Single-photon generation and detection
The detection and generation of single photons has seen an upsurge in interest in recent years as new scientific fields of research, for example quantum information processing, have been established.Expand
Ranging and Three-Dimensional Imaging Using Time-Correlated Single-Photon Counting and Point-by-Point Acquisition
Time-correlated single-photon counting techniques have been applied to time-of-flight ranging and imaging. This article describes recent progress in photon-counting systems performing surface mappingExpand
Single-photon three-dimensional imaging at up to 10 kilometers range.
High-resolution three-dimensional images of various targets acquired over ranges between 800 metres and 10.5 km demonstrate long-range depth and intensity profiling, feature extraction and the potential for target recognition. Expand
Design and performance of an InGaAs-InP single-photon avalanche diode detector
This paper describes the design, fabrication, and performance of planar-geometry InGaAs-InP devices which were specifically developed for single-photon detection at a wavelength of 1550 nm. GeneralExpand
Quantum key distribution system clocked at 2 GHz.
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 ofExpand
Ge-on-Si Single-Photon Avalanche Diode Detectors: Design, Modeling, Fabrication, and Characterization at Wavelengths 1310 and 1550 nm
The design, modeling, fabrication, and characterization of single-photon avalanche diode detectors with an epitaxial Ge absorption region grown directly on Si are presented. At 100 K, a single-photonExpand
Laser-based distance measurement using picosecond resolution time-correlated single-photon counting
In this paper, we report results obtained with a time-of-flight ranging/scanning system based on time-correlated single-photon counting. This system uses a pulsed picosecond diode laser and detectsExpand
