摘要：
We report an entanglement concentration scheme in which a maximally entangled Bell-state can be obtained from two pairs of partially (or non-maximally) entangled photons. Since this scheme is built only upon linear optics and does not require photon-number resolving detectors, it should be applicable in experimental implementations of various quantum information protocols which require maximally entangled Bell-states.
