+ID281 Superconducting Nanowire Single Photon Detector +SNSPD +Infrared Photon Detection +Quantum Information
Background
As interests in Quantum Communication and Quantum Information has increased, so to has the demand for high efficency single photon detection systems. High efficiency systems are desired for their abilitiy not only to detect the incoming signals, but also provide experimental assurance - as often, we are testing new devices, electronic or optical components, and require reliable and robust systems to ensure the accuracy of our experimental data. Quantum Information or quantum computing systems demand a reliable quantum efficiency detection rate as it directly translated to the reliability of the system in transmitting or decrypting information.
Introduction
This is especially problematic over long physical distances or when the input signal is passed through complex layers of electrical or optical components that are critical in the operation as attenuation becomes a major factor and experimental concern. Typical infrared single photon dectors have a quantum efficiency of 25%, making SNSPD systems the detector of choice for quantum information applications . Superconducting Nanowire Systems typically reach >85% system detection efficiencies, with signifcantly more powerful time tagging electronics.

Application
Superconducting Nanowire systems are often reliable detectors employed in these situations. Describing a recent use case, the ID281 - SNSPD system was used in a test setup for quantum key distribution. Key factors leading to the adoption of the ID281 System was a optimized system detection efficiency of more than 85% for the specified wavelength range along with a multiple channel configuration allowing for ease of integration into complex fiber networks or systems. The high detection efficiency contributed to the viability of experimental procedures of which signal loss was notable due to attenuation.
