Linear optical implementation of a single mode quantum filter and generation of multi-photon polarization entangled state

Quantum Physics 2009-11-07 v1

Abstract

We propose a scheme to implement a single-mode quantum filter, which selectively eliminates the one-photon state in a quantum state α0>+β1>+γ2>\alpha|0>+\beta|1>+\gamma|2>. The vacuum state and the two photon state are transmitted without any change. This scheme requires single-photon sources, linear optical elements and photon detectors. Furthermore we demonstrate, how this filter can be used to realize a two-qubit projective measurement and to generate multi-photon polarization entangled states.
