高斯光源的量子照明

Quantum Illumination with a generic Gaussian source

Athena Karsa, Gaetana Spedalieri, Quntao Zhuang, Stefano Pirandola

摘要:

为了降低量子照明对纠缠的要求,我们研究了发送端的高斯态族,以及接收端的最优联合量子测量的性能.我们发现,最大的纠缠是不是严格必要的,以实现量子优势的相干态发射机的经典基准,在对称和非对称假设检验的设置。在进行这种量子经典比较的同时,我们还研究了一个合适的参数机制,用于潜在的短程雷达(或扫描仪)应用。

英文摘要:

With the aim to loosen the entanglement requirements of quantum illumination, we study the performance of a family of Gaussian states at the transmitter, combined with an optimal and joint quantum measurement at the receiver. We find that maximal entanglement is not strictly necessary to achieve quantum advantage over the classical benchmark of a coherent-state transmitter, in both settings of symmetric and asymmetric hypothesis testing. While performing this quantum-classical comparison, we also investigate a suitable regime of parameters for potential short-range radar (or scanner) applications.
