Scheme for generation of three-photon entangled W state assisted by cross-Kerr nonlinearity and quantum dot.

We represent an optical scheme using cross-Kerr nonlinearities (XKNLs) and quantum dot (QD) within a single-sided optical cavity (QD-cavity system) to generate three-photon entangled W state containing entanglement against loss of one photon of them. To generate W state (three-photon) with robust en... View More
