摘要:

量子封锁和纠缠在量子信息和量子通信中起着重要的作用,量子封锁是产生单光子(声子)的有效机制,而纠缠是量子信息处理的重要资源。在这项工作中,我们提出了一种方法,以产生单一的纠缠光子-声子对的混合光机械系统。我们发现,光子封锁,声子封锁,光子-声子关联和纠缠可以通过原子-光子-声子(三方)相互作用,在共振原子驱动下观察。关联和纠缠的单光子和单声子,即,单个纠缠光子-声子对,可以在弱和强三方相互作用体系中产生。我们的研究结果可能在开发高度复杂的量子网络中有重要的应用。

英文摘要:

Quantum blockade and entanglement play important roles in quantum information and quantum communication as quantum blockade is an effective mechanism to generate single photons (phonons) and entanglement is a crucial resource for quantum information processing. In this work, we propose a method to generate single entangled photon-phonon pairs in a hybrid optomechanical system. We show that photon blockade, phonon blockade, and photon-phonon correlation and entanglement can be observed via the atom-photon-phonon (tripartite) interaction, under the resonant atomic driving. The correlated and entangled single photons and single phonons, i.e., single entangled photon-phonon pairs, can be generated in both the weak and strong tripartite interaction regimes. Our results may have important applications in the development of highly complex quantum networks.
