Possibility of producing the event-ready two-photon polarization entangled state with normal photon detectors
Xiang‐Bin Wang · Physical Review A · 2003
We propose a scheme to produce the maximally two-photon polarization entangled state with single-photon sources and the passive linear optics devices. In particular, our scheme only requires the normal photon detectors which distinguish the vacuum and non-vacuum Fock number states. A sophisticated photon detector distinguishing between one-photon state and two-photon state is unnecessary in the scheme.
