We present a linear optical protocol for multiparty remote state preparation (MRSP) in terms of optical elements. MRPS is a procedure for multiparty collaboration with each other to remote preparation of a known quantum state to a distant party. We show that it is possible to achieve unity fidelity remote preparation of the polarization state using optical elements. This protocol may be used for converging the split information at one point.
We report on the generation of continuous-variable hyperentanglement of polarization and orbital angular momentum with a type II optical parametric oscillator. By compensating for the astigmatism between spatial modes, we produce an entangled pair of Hermite-Gauss beams. From correlations measurements, we verify the existence of continuous-variable hyperentanglement by the general entanglement criterion as well as by the continuous-variable version of the Peres-Horodecki criterion visualized on an equivalent Poincaré sphere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
