Abstract
An experimental scheme for concentrating entanglement in partially entangled photon pairs is proposed. A practical realization of the proposed scheme is discussed, which uses imperfect photon detectors and spontaneous parametric down-conversion as a photon source. This scheme also works for purifying a class of mixed states.
