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

Remote creation of hybrid entanglement between particle-like and wave-like optical qubits
TL;DR: In this paper, a particle-like subsystem and a wave-like one are generated through the heralding detection of a single photon in an indistinguishable fashion at a central station, which enables information to be converted from one Hilbert space to the other via teleportation, and hence permits remote quantum processors based on different encodings to be connected.

Nondestructive Detection of an Optical Photon
TL;DR: An experimental system capable of detecting a single photon without destroying it is described and the large single-photon nonlinearity of the experiment should enable the development of photonic quantum gates and the preparation of exotic quantum states of light.
