Phys. Rev. A 65, 053818 (2002) [6 pages]Conditional generation of N-photon entangled states of lightReceived 29 October 2001; revised 29 January 2002; published 8 May 2002 We propose a scheme for conditional generation of two-mode N-photon path-entangled states of traveling light field. These states may find applications in quantum optical lithography and they may be used to improve the sensitivity of interferometric measurements. Our method requires only single-photon sources, linear optics (beam splitters and phase shifters), and photodetectors with single-photon sensitivity. © 2002 The American Physical Society URL:
