Interference enhanced polarization entanglement and the concept of an Entangled-Photon Laser
arXiv:quant-ph/0103056
Abstract
Inspired by laser operation, we address the question of whether stimulated emission into polarization entangled modes can be achieved. We describe a state produced by stimulated emission of the singlet Bell state and propose a setup for creating it. As a first important step towards an entangled-photon laser we demonstrate experimentally interference-enhanced polarization entanglement.
