TLDR
In this article, a fiber-coupled single-photon detection system using amorphous tungsten silicide superconducting nanowire detectors was developed, and the system detection efficiency was higher than 90% in the wavelength range between 1520 nm and 1610 nm.Abstract:
Researchers develop a fiber-coupled single-photon-detection system using amorphous tungsten silicide superconducting nanowire single-photon detectors. The system detection efficiency is higher than 90% in the wavelength range between 1520 nm and 1610 nm. The device dark-count rate, timing jitter and reset time are 1 cps, 150 ps and 40 ns, respectively.read more

TL;DR: In this paper, the authors proposed a device-independent quantum key distribution protocol exploiting single-photon sources and heralding-type architectures, where the heralding process is designed so that transmission losses become irrelevant for security, and the use of single photon sources for entanglement distribution, instead of standard entangled-pair generation schemes, provides significant improvements on the attainable key rates and distances over previous proposals.

TL;DR: A number of physical systems, spanning much of modern physics, are being developed for this task, ranging from single particles of light to superconducting circuits, and it is not yet clear which, if any, will ultimately prove successful as discussed by the authors.

TL;DR: In this article, a supercurrent-assisted hotspot-formation mechanism for ultrafast detection and counting of visible and infrared photons is presented, where a photon-induced hotspot leads to a temporary formation of a resistive barrier across the superconducting sensor strip and results in an easily measurable voltage pulse.
