量子网络中的参考系一致性

Reference frame agreement in quantum networks

Tanvirul Islam, Loïck Magnin, Brandon Sorg, Stephanie Wehner

摘要:

为了在量子网络中有效地传递信息,所有网络节点应该共享一个公共的参考系。在这里,我们建议研究量子网络中的m个节点如何从头开始建立一个共同的参考系,即使其中t个节点可能是任意错误的。我们提出了一个协议,允许所有正确运行的节点同意一个共同的参考系,只要不超过t < m/3节点有故障。我们的协议还具有吸引人的属性,它允许任何现有的两方协议的参考系协议被提升到一个协议的量子网络。

英文摘要:

In order to communicate information in a quantum network effectively, all network nodes should share a common reference frame. Here, we propose to study how well m nodes in a quantum network can establish a common reference frame from scratch, even though t of them may be arbitrarily faulty. We present a protocol that allows all correctly functioning nodes to agree on a common reference frame as long as not more than t < m/3 nodes are faulty. Our protocol furthermore has the appealing property that it allows any existing two-party protocol for reference frame agreement to be lifted to a protocol for a quantum network.
