论文摘要
量子纠缠是量子信息的重要资源。在这里，我们提出了一种在混合原子纤维系统中{准备}原子量子纠缠的方法。使用量子ZENO动力学方法，系统进化状态始终分为一系列由黑暗和明亮状态组成的Zeno不变{subpaces}。通过选择系统的初始状态，明亮的状态都被忽略了，只有黑暗状态才能建立有效的哈密顿式。通过调整系统参数，可以通过一个步骤实现两个原子的多维纠缠，两种原子铃状状态和三原子GHz状态。我们的建议提供了一种使用黑暗状态执行量子信息处理的方法。
Quantum entanglement is important quanum resources in quantum information sicence. Here we propose an approach to {preparing} atomic quantum entanglement in a hybrid atom-cavity-fiber system. Using quantum Zeno dynamics method, the system evolution states are always split into a series of Zeno invariant {subspaces} consisting of dark and bright states. By choosing the initial state of the system, the bright states are all neglected and only dark states are kept to build the effective Hamiltonian. By tuning the system parameters, two-atom multiple-dimensional entanglement, two-atom Bell state, and three-atom GHZ state can be realized by one step. Our proposal provides a way to perform quantum information processing with dark states.
