论文摘要
我们使用来自量子状态歧视的技术对量子传感器网络进行建模。量子检测器与环境之间的相互作用是由单一操作员描述的,我们将假设最多有一个检测器确实相互作用。任务是确定哪一个或是否没有。这涉及选择检测器的初始状态和测量。我们考虑同时测量所有检测器的全球测量值。我们发现纠缠的初始状态可以提高检测概率,但是随着检测器数量的增加,该优势降低了。
We model a quantum sensor network using techniques from quantum state discrimination. The interaction between a qubit detector and the environment is described by a unitary operator, and we will assume that at most one detector does interact. The task is to determine which one does or if none do. This involves choosing an initial state of the detectors and a measurement. We consider global measurements in which all detectors are measured simultaneously. We find that an entangled initial state can improve the detection probability, but this advantage decreases as the number of detectors increases.
