The feasible generation of entangled photon states by using linear optical elements

Abstract
We present a feasible scheme to produce a polarization-entangled photon states 12(|H>|V>+|V>|H>) in a controllable way. This scheme requires single-photon sources, linear optical elements and photon detectors. It generates the entanglement of spatially separated photons. The interaction takes place in the photon detectors. We also show that the same idea can be used to produce the entangled N-photon state 12(|0,N>+|N,0>)
