    "abstract": "We propose a scheme to produce the maximally two photon polarization\nentangled state(EPR state) with single photon sources and the linear optics\ndevices. In particular, our scheme requires the photon detectors only to\ndistinguish the vacuum and non-vacuum Fock number states. A sophisticated\nphoton detector distinguishing one or two photon states is unnecessary.",
