Enlarge the scale of W state by connecting multiple existed W states

Enlarge the scale of W state by connecting multiple existed W states We propose a simple scheme to generate large-scale W state. With the cross-phase modulation, we design a photon number resolving discrimination. This discrimination, associated with some single-photon operations, is enough to connect the existed W states. No more two-photon or multi-photon operations are required. This scheme is powerful and flexible for connecting arbitrary number of W states. It is therefore suitable for creating large-scale W state with the current technology. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals
