Nonlocal Nondegenerate Optical Parametric Amplifier Based on Genuine Multipartite Entanglement
arXiv:0711.1646 · doi:10.1103/PhysRevA.76.064301
Abstract
We propose a new scheme for realizing nonlocal nondegenerate optical parametric amplifier by means of genuine four-mode entanglement. The nondegenerate optical parametric amplifier is regarded as a unitary transformation from two input fields to two outputs. Two inputs and two outputs are located at the remote stations respectively. Employing off-line four-mode entanglement, homodyne detection, classical communication and local displacement, the nonlocal nondegenerate optical parametric amplifier can be achieved. This scheme can be implemented with a setup that is experimentally accessible at present.
