论文摘要
Josephson参数放大器（JPA）工程是量子两模式挤压雷达（QTMS）中的重要组成部分，例如增强雷达性能和检测范围或带宽。在这项研究中，我们将量子理论应用于集中QTMS雷达设计的研究领域。我们应用工程的JPA（EJPA）来增强量子雷达（QR）的性能。我们使用使用信号和惰轮之间的相关性，并提出了在室温下维持纠缠的策略。我们定义QTMS雷达的量子信号噪声比（SNR）和检测范围方程。工程JPA导致量子雷达性能的显着改善，即大约6 dB的量子SNR的大大提高，通过较少的通道检测可能性有了很大的提高，QTMS雷达范围的大幅度提高，从常规的JPA中的半米从一米中提高到当前研究中的半米。
Josephson parametric amplifier (JPA) engineering is a significant component in the quantum two-mode squeezed radar (QTMS), to enhance, for instance, radar performance and the detection range or bandwidth. In this study, we apply quantum theory to a research domain focusing the design of QTMS radar. We apply engineered JPA (EJPA) to enhance the performance of a quantum radar (QR). We investigate the correlation between the signal and idler using and we propose strategies for maintaining entanglement at room temperature. We define the quantum signal-to-noise ratio (SNR) and detection range equations of the QTMS radar. The engineering JPA, leads to a remarkable improvement of the quantum radar performance, i.e. a large enhancement in quantum SNR of about 6 dB, a substantial improvement in the probability of detection through far fewer channels, and a huge increase in QTMS radar range, from half a meter in the conventional JPA to 482 m in the current study.
