Super-Conducting Single Photon Detector

Brief Description
A very fast, very sensitive single-photon, time-resolving detector for photons in wavelengths from the visible to the far infrared, using a super-conducting material.

Applications
Single photon detectors may be used in systems for free space and satellite communications and studies of weak luminescence and semiconductor device testing.    They may also be used in quantum cryptographic systems, which would support the most secure method of communication possible, guaranteed by the inviolability of the laws of quantum mechanics.

Advantages
The principal benefit of this invention, which uses a superconducting material, is the ability to detect photons in the infrared wavelengths typically used in optical communication.  Other available single-photon detectors function only in the visible or shorter wavelengths.
