    "abstract": "We propose a feasible scheme to create $n$-party ($n\\geq 2$)\npolarization-entangled photon states in a controllable way. The scheme requires\nonly single-photon sources, single-photon quantum non-demolition measurement\n(SP-QNDM) and simple linear optical elements, usually with high perfections.\nThe SP-QNDM acts as a non-destructive projection measurement onto the wanted\nentangled states and filters out the unwanted terms. Our scheme in fact\nrealizes entanglement of non-interacting photons; the interaction occurs only\nimplicitly in the optical elements and SP-QNDM. We also briefly consider\npurification of mixed single-photon states within our scheme.",
