在网络节点之间可靠地分配纠缠的能力是开发有效的量子通信协议和实现有用的量子网络的基本要求。在不同的背景下，已经证明了两个远程系统可以通过与载体系统的局部相互作用而纠缠，该载体系统总是保持在相对于这些远程粒子的可分离状态。我们开发了一种策略，通过可分离的载体，可以应用到任何数量的网络节点，以实现各种纠缠分布模式的纠缠分布。我们表明，我们的协议的结果在多方纠缠，而调解的过程中的载体总是在一个可分离的状态相对于网络。我们提供的例子展示了我们的方法的灵活性，并提出了一个方案的原则，该协议的实验演示。
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.
