    "abstract": "We present a feasible scheme to produce a polarization-entangled photon\nstates $\\frac{1}{\\sqrt{2}}(|H\u003e|V\u003e+|V\u003e|H\u003e)$ in a controllable way. This scheme\nrequires single-photon sources, linear optical elements and photon detectors.\nIt generates the entanglement of spatially separated photons. The interaction\ntakes place in the photon detectors. We also show that the same idea can be\nused to produce the entangled $N$-photon state\n$\\frac{1}{\\sqrt{2}}(|0,N\u003e+|N,0\u003e)$",
