Abstract

We propose a protocol for the controlled generation of four-photon polarization-entangled decoherence-free states with a certain success probability. The proposed setup involves simple linear optical elements, two single-photon polarzaition entangled states, a pair of two-photon polarization entangled states, and conventional photon detectors that only distinguish the vacuum and nonvacuum Fock number states. This makes the protocol more realizable in experiments.
