摘要：
在本文中，我们引入了一种量子安全单像素成像（QS-SPI）技术，旨在抵御欺骗攻击，即对手试图用虚假信号欺骗成像系统。与以往施加阈值错误率限制其运行的量子安全协议不同，即使存在真实信号，我们的方法不仅能识别欺骗攻击，还能促进真实图像的重建。我们的方法涉及分析光子对的特定模式相关性，该相关性与用于图像构建的模式无关，以检查安全性。通过此分析，我们可以识别攻击所针对的图像区域和欺骗攻击的类型，从而实现真实图像的重建。我们提供了一个利用光子对偏振相关性的原理验证演示，展示了即使在欺骗信号比真实信号强2000倍的条件下，也能成功重建图像。我们期望我们的方法能应用于量子安全信号处理，如量子目标检测或测距。
英文摘要：
In this paper, we introduce a quantum-secured single-pixel imaging (QS-SPI) technique designed to withstand spoofing attacks, wherein adversaries attempt to deceive imaging systems with fake signals. Unlike previous quantum-secured protocols that impose a threshold error rate limiting their operation, even with the existence of true signals, our approach not only identifies spoofing attacks but also facilitates the reconstruction of a true image. Our method involves the analysis of a specific mode correlation of a photon-pair, which is independent of the mode used for image construction, to check security. Through this analysis, we can identify both the targeted image region by the attack and the type of spoofing attack, enabling reconstruction of the true image. A proof-of-principle demonstration employing polarization-correlation of a photon-pair is provided, showcasing successful image reconstruction even under the condition of spoofing signals 2000 times stronger than the true signals. We expect our approach to be applied to quantum-secured signal processing such as quantum target detection or ranging.
