论文摘要
虽然量子照明(QI)可以在目标检测中提供量子增强,但其执行目标范围的潜力尚不清楚。由于其功能依赖于返回信号与保留的惰轮之间的联合测量,因此未知的返回时间使基于QI的协议难以实现。本文根据多个量子假设测试和量子增强的通道位置查找(CPF)的最新发展概述了一种基于QI的量子目标范围的潜在方法。将CPF应用于时间垃圾箱,发现量子目标范围的误差概率上有上限。但是,使用能量考虑因素,我们表明,对于这种方案,量子优势可能无法物理上实现。
While quantum illumination (QI) can offer a quantum-enhancement in target detection, its potential for performing target ranging remains unclear. With its capabilities hinging on a joint-measurement between a returning signal and its retained idler, an unknown return time makes a QI-based protocol difficult to realise. This paper outlines a potential QI-based approach to quantum target ranging based on recent developments in multiple quantum hypothesis testing and quantum-enhanced channel position finding (CPF). Applying CPF to time bins, one finds an upper-bound on the error probability for quantum target ranging. However, using energetic considerations, we show that for such a scheme a quantum advantage may not physically be realised.
