Scheme for preparation of nonmaximal entanglement between two atomic ensembles

Abstract

We propose an experimentally feasible scheme to generate nonmaximal entanglement between two atomic ensembles. The degree of entanglement is readily tunable. The scheme involves laser manipulation of atomic ensembles, adjustable quarter- and half-wave plates, beam splitter, polarizing beam splitters, and single-photon detectors, and well fits the status of the current experimental technology. Finally we use the nonmaximally entangled state of ensembles to demonstrate quantum nonlocality by detecting the Clauser-Horne-Shimony-Holt inequality.

We propose an experimentally feasible scheme to generate nonmaximal entanglement between two atomic ensembles. The degree of entanglement is readily tunable. The scheme involves laser manipulation of atomic ensembles; the setup includes adjustable quarter- and half-wave plates, a beam splitter, polarizing beam splitters, and single-photon detectors, and fits well the state of current experimental technology. Finally, we use the nonmaximally entangled state of ensembles to demonstrate quantum nonlocality by detecting the Clauser–Horne–Shimony–Holt inequality.

Scheme for preparation of multi-partite entanglement of atomic ensembles

Peng Xue, Zhihao Bian

We show a scheme of preparing multipartite W type of maximally entangled states among many atomic ensembles with the generation time increasing with the party number only polynomially. The scheme is based on laser manipulation of atomic ensembles and single-photon detection, and fits well the status of the current experimental technology. We also show one of the applications of this kind of W state, demonstrating Bell theorem without inequalities.

We propose an experimentally feasible scheme to generate general entangled states between atoms in spatially separate cavities, and then show one of the applications---a secure communication allowing asymptotically key distribution and quasisecure direct communication. The scheme involves laser manipulation of atoms in a high-$Q$ cavity, adjustable quarter- and half-wave plates, beam splitter, polarizing beam splitters, and single-photon detectors, and well fits the status of the current experimental technology.
