Linear Optical Scheme for Local Transformation of Bipartite Resources into a Multipartite W State

A linear optical scheme is proposed to convert N−1 (N≥3) entangled two-photon pairs distributed among N parties into a N-photon W state using local operations and classical communication. In the scheme an arbitrary large-scale entanglement webs for photonic W state among multiple parties can be achieved with the certain success probability by locally operating two photons held by each of the parties. The scheme is feasible and within the reach of current experimental technology.
