Advances in semiconductor single photon avalanche diode detectors have enabled an expansion in photon-counting application areas in the near-infrared. Of particular relevance is the application area of quantum key distribution in which secure encryption keys can be shared between users using information derived from streams of encoded single-photons. We report progress towards the objective of a practical, high efficiency detector at the strategically important 1550nm wavelength band.

Abstract
Advances in semiconductor single photon avalanche diode detectors have enabled an expansion in photon-counting application areas in the near-infrared. Of particular relevance is the application area of quantum key distribution in which secure encryption keys can be shared between users using information derived from streams of encoded single-photons. We report progress towards the objective of a practical, high efficiency detector at the strategically important 1550nm wavelength band.File in questo prodotto:
