论文摘要
尽管纠缠被有损的传播破坏了，但已知纠缠会增强目标检测。最近，[物理学。莱特牧师。 128，010501（2022）]提出了一个量子脉冲压缩雷达，以扩展纠缠的益处，以对目标范围估计。在雷达应用中，目标的许多其他方面都是感兴趣的，包括角度，速度和横截面。在这项研究中，我们提出了一种双收率雷达方案，该方案采用了较高的时间带宽产品微波脉冲，该脉冲与接收器上可用的前共享参考信号纠缠在一起，以研究远处对象的方向并表明，与在同一参数下方的经典参数设置相比，通过纠缠的方向分辨能力可显着提高。我们将此量子雷达的适用场景确定为短距离和高频，这可以在合理的集成时间内纠缠的好处。
Entanglement has been known to boost target detection, despite it being destroyed by lossy-noisy propagation. Recently, [Phys. Rev. Lett. 128, 010501 (2022)] proposed a quantum pulse-compression radar to extend entanglement's benefit to target range estimation. In a radar application, many other aspects of the target are of interest, including angle, velocity and cross section. In this study, we propose a dual-receiver radar scheme that employs a high time-bandwidth product microwave pulse entangled with a pre-shared reference signal available at the receiver, to investigate the direction of a distant object and show that the direction-resolving capability is significantly improved by entanglement, compared to its classical counterpart under the same parameter settings. We identify the applicable scenario of this quantum radar to be short-range and high-frequency, which enables entanglement's benefit in a reasonable integration time.
