Abstract: Various embodiments of the present invention are directed to compact systems for generating polarization-entangled photons. In one embodiment of the present invention, a non-degenerate, polarization-entangled photon source comprises a half-wave plate that outputs both a first pump beam and a second pump beam, and a first beam displacer that directs the first pump beam into a first transmission channel and the second pump beam into a second transmission channel. A down-conversion device converts the first pump beam into first signal and idler photons and converts the second pump beam into second signal and idler photons. A second beam displacer directs both the first signal and idler photons and the second signal and idler photons into a single transmission channel. A dichroic mirror directs the first and second signal photons to a first fiber optic coupler and the first and second idler photons to a second fiber optic coupler.

Abstract: A quantum-dot photon turnstile device is capable of producing a stream of regulated and directed single pairs of photons with opposite circular polarizations. This device operates by injecting pairs of electrons and holes, alternately, into a single quantum dot, where they combine to form photons. The device will efficiently and reliably produce a directed beam of such photons at regular time intervals. It will be able to operate at high frequency and at high temperature. Such a stream of regulated photon pairs will be useful in quantum cryptography, quantum computing, low-power optical communications, as a light standard, and in many other areas of technology and fundamental science.
