Equivalent efficiency of a simulated photon-number detector
Homodyne detection is considered as a way to improve the efficiency of communication near the singlephoton level. The current lack of commercially available infrared photon-number detectors significantly reduces the mutual information accessible in such a communication channel. We consider simulating direct detection via homodyne detection. We find that our particular simulated direct detection...

متن کاملAn avalanche-photodiode-based photon-number-resolving detector
Avalanche photodiodes are widely used as practical detectors of single photons. Although conventional devices respond to one or more photons, they cannot resolve the number in the incident pulse or short time interval. However, such photon number resolving detectors are urgently needed for applications in quantum computing, communications and interferometry, as well as for extending the applica...
متن کاملRoom temperature photon number resolving detector for infared wavelengths.
In this paper we present a photon number resolving detector at infrared wavelengths, operating at room temperature and with a large dynamic range. It is based on the up-conversion of a signal at 1559 nm into visible wavelength and on its detection by a thermoelectrically cooled multi-pixel silicon avalanche photodiodode, also known as a Silicon Photon Multiplier. With the appropriate up-convers...
متن کاملPhoton -counting Reticontm Detector
For applications in faint -object spectroscopy at the Mt. Hopkins Observatory, a photon counting detector has been built using a dual 936 Reticon diode array fibre -optically coupled to a high -gain image intensifier package. The electronic signal processing follows closely the design of Shectman; the diode array is scanned every millisecond, each frame is subtracted from the previous to minimi...
