Genuine Multipartite Quantum Steering can be Generated by Enhanced Raman Scattering without Optical Cavity
摘要
Multipartite quantum steering correlation among Raman scattering beams generated by the enhanced Raman scattering process is investigated. In this single-pass nonlinear process, without an optical resonant cavity, Raman scattering beams of the same order can be significantly enhanced through differential amplification of pump, resulting in enhanced Raman scattering beams. Based on the multipartite quantum steering correlation criterion, tripartite quantum steering and five-partite quantum steering can be obtained by the first-order Raman scattering and the second-order Raman scattering, respectively. This scheme of the generation of multipartite quantum steering enriches the types of quantum manipulation and can be applied to quantum information work such as quantum networks.
