We build and test a single-photon detector based on a Si avalanche photodiode Excelitas 30902SH thermoelectrically cooled to −100 ∘ C. Our detector has dark count rate below 1 Hz, 500 μ m $500\ \mu\mathrm{m}$ diameter photosensitive area, photon detection efficiency around 50%, afterpulsing less than 0.35%, and timing jitter under 1 ns. These characteristics make it suitable for long-distance free-space quantum communication links, which we briefly discuss. We also report an improved method… Expand

Ultra-low noise single-photon detector based on Si avalanche photodiode.
TLDR
While afterpulsing increased as the photodiode temperature was decreased, total afterpulse probability did not become significant due to detector's relatively long deadtime in a passively-quenched scheme. Expand

TLDR
The authors' spaceborne, low-noise SPDs established a feasible satellite-based up-link quantum communication that was validated on the quantum experiment science satellite platform and open new windows of opportunities for space research and applications in deep-space optical communications, single-photon laser ranging, as well as for testing the fundamental principles of physics in space.

Single-photon detection beyond 1 µm: performance of commercially available germanium photodiodes.
TLDR
Germanium avalanche photodiodes (APD's) working biased above the breakdown voltage detect single optical photons in the near-infrared wavelength range, and it is shown that some selected APD's achieve an 85-ps time resolution in the detection of optical photons at a 1.3-µm wavelength, which corresponds to a timing-equivalent bandwidth of 1.8 GHz.

TLDR
Proton radiation tests of various models of avalanche photodiodes and one model of photomultiplier tube potentially suitable for satellite-based quantum communications demonstrate significant increases in dark count rate (DCR) due to radiation-induced damage, many orders of magnitude higher than the 200 counts per second required for ground-to-satellite quantum communications.
