论文摘要
在网络节点之间可靠分布纠缠的能力是开发有效量子通信协议和实现有用量子网络的必不可少的必需品。在不同的情况下,已经证明了两个远程系统可以通过与载体系统相对于这种遥远的粒子始终保持可分离状态的局部交互纠缠。我们通过可分开的载体制定了纠缠分布的策略,该策略可以应用于任何数量的网络节点,以实现各种纠缠分布模式。我们表明,我们的协议会导致多部分纠缠,而介导过程的载体始终处于相对于网络的可分离状态。我们提供了展示我们方法灵活性的例子,并提出了协议实验证明的原理方案。
The ability to reliably distribute entanglement among the nodes of a network is an essential requirement for the development of effective quantum communication protocols and the realization of useful quantum networks. It has been demonstrated, in different contexts, that two remote systems can be entangled via local interactions with a carrier system that always remains in a separable state with respect to such distant particles. We develop a strategy for entanglement distribution via separable carriers that can be applied to any number of network nodes to achieve various entanglement distribution patterns. We show that our protocol results in multipartite entanglement, while the carrier mediating the process is always in a separable state with respect to the network. We provide examples showcasing the flexibility of our approach and propose a scheme of principle for the experimental demonstration of the protocol.
