    "abstract": "A simple experimental setup consisting of a spontaneous parametric\ndown-conversion source and passive linear optics is proposed for conditional\npreparation of a maximally entangled polarization state of two photons.\nSuccessful preparation is unambiguously heralded by coincident detection of\nfour auxiliary photons. The proposed scheme utilizes the down-conversion term\ncorresponding to the generation of three pairs of photons. We analyze imperfect\ndetection of the auxiliary photons and demonstrate that its deleterious effect\non the fidelity of the prepared state can be suppressed at the cost of\ndecreasing the efficiency of the scheme.",
