    "abstract": "We propose a scheme to implement a single-mode quantum filter, which\nselectively eliminates the one-photon state in a quantum state\n$\\alpha|0\u003e+\\beta|1\u003e+\\gamma|2\u003e$. The vacuum state and the two photon state are\ntransmitted without any change. This scheme requires single-photon sources,\nlinear optical elements and photon detectors. Furthermore we demonstrate, how\nthis filter can be used to realize a two-qubit projective measurement and to\ngenerate multi-photon polarization entangled states.",
