Use of entanglement in quantum optics
Michael Horne, Herbert Joseph Bernstein, Daniel M. Greenberger +1 more
Several recent demonstrations of two-particle interferometry are reviewed and shown to be examples of either color entanglement or beam entanglement. A device, called a number filter, is described and shown to be of value in preparing beam entanglements. Finally, we note that all three concepts (color and beam entaglement, and number filtering) may be extended to three or more particles.
