论文摘要
多部分纠缠在量子互联网的设计中起着至关重要的作用，因为它有显着提高网络性能的潜力。在本文中，我们为多方状态设计了一个纠缠访问控制协议，该协议表现出几种有吸引力的功能。具体而言，设计的协议能够以分布式的方式共同提取来自原始多部分纠缠状态的EPR对由网络节点集共享，并单次确定发射机节点的身份和使用提取的EPR对负责的接收器节点。此外，该协议避免将带有纠缠访问控制权的信号传递委托给经典网络，除了EPR提取和QUBIT传送所需的不可避免的经典通信外。最后，该协议支持访问节点的纠缠的匿名性。
Multipartite entanglement plays a crucial role for the design of the Quantum Internet, due to its potentiality of significantly increasing the network performance. In this paper, we design an entanglement access control protocol for multipartite state, which exhibits several attractive features. Specifically, the designed protocol is able to jointly extract in a distributed way an EPR pair from the original multipartite entangled state shared by the set of network nodes, and to univocally determines the identities of the transmitter node and the receiver node in charge of using the extracted EPR pair. Furthermore, the protocol avoids to delegate the signaling arising with entanglement access control to the classical network, with the exception of the unavoidable classical communications needed for EPR extraction and qubit teleportation. Finally, the protocol supports the anonymity of the entanglement accessing nodes.
