    "abstract": "We present a concentration and purification scheme for nonmaximally entangled\npure and mixed porization entangled state. We firstly show that two distant\nparties Alice and Bob first start with two shared but less entangled photon\npure states to produce a four photon GHZ state, and then perform a 45\npolarization measurement onto one of the two photons at each location such that\nthe remaining two photon are projected onto a maximally entangled state. We\nfurther show the scheme also can be used to purify a class of mixed\npolarization-entangled state.",
