论文摘要
我们通过为它们提供了处理超跨任务和超级解决方案的可能性，展示了如何建立基于标准和基于纠缠的真实量子的量子网络。它们功能的扩展依赖于量子控制寄存器，该寄存器不仅指定了网络的任务，还指定了相应的超级式方式的相应权重。尽管通常不可能地将连贯的控制添加到经典任务中，例如发送或测量或不进行测量，但我们介绍了能够在某些条件下模仿这种行为的协议。我们通过始终在所需状态或正确选择的虚拟状态执行经典任务来实现这一目标。我们提供了几个示例，并证明了任务的外部控制量子叠加提供了通常被认为是单个功能的新可能性和优势。例如，可以准备在网络的不同节点之间共享不同目标状态配置的叠加，也可以在不同路径的叠加或不同目的地之间发送量子信息。
We show how to make quantum networks, both standard and entanglement-based, genuine quantum by providing them with the possibility of handling superposed tasks and superposed addressing. This extension of their functionality relies on a quantum control register, which specifies not only the task of the network, but also the corresponding weights in a coherently superposed fashion. Although adding coherent control to classical tasks, such as sending or measuring -or not doing so-, is in general impossible, we introduce protocols that are able to mimick this behavior under certain conditions. We achieve this by always performing the classical task, either on the desired state or a properly chosen dummy state. We provide several examples, and show that externally controlling quantum superposition of tasks offers new possibilities and advantages over usually considered single functionality. For instance, superpositions of different target state configurations shared among different nodes of the network can be prepared, or quantum information can be sent among a superposition of different paths or to different destinations.
