Practicable scheme to generate the three photon entangled state with linear optical elements

摘要

This paper proposed practicable scheme for generation of the three photon entangled states without any nonlinear optical process. The three-photon entanglement can be achieved by using linear optical elements with post selection based on the photons interferometry. The success probability of proposed method is 3/16, higher than the previous methods using the linear optical system.
