• Abstract: In this paper, we propose a novel quantum-secured single-pixel imaging method that utilizes non-classical correlations of a photon pair. Our method can detect any attempts to deceive it by exploiting a non-classical correlation of photon pairs while rejecting strong chaotic light illumination through photon heralding. A security analysis based on polarization-correlation has been conducted, demonstrating that our method has improved security compared to existing quantum-secured imaging. More specifically, a partial deceiving attack, which sends a mixture of a true and a false signal, can be detected with our proposed analysis, while currently employed methods cannot. We also provide proof-of-principle demonstrations of our method and trustworthy images reconstructed using our security analysis. Our method can be developed using matured techniques used in quantum secure communication, thus offering a promising direction for practical applications in secure imaging.

Unlike previous quantum-secured protocols that impose a threshold error rate limiting their operation, our approach not only identifies spoofing attacks but also facilitates the reconstruction of a true image.

  Non-Gaussian states of an optical field are important as a proposed resource in quantum information applications.

We conclude that states with strong Wigner negativity can be prepared at high rates by this technique under experimentally attainable conditions.

  We find that there exists compliance between perturbations and prediction confidence, which guides us to detect few-perturbation attacks from the aspect of prediction confidence. We propose a method beyond image space by a two-stream architecture, in which the image stream focuses on the pixel artifacts and the gradient stream copes with the confidence artifacts.

• Security of quantum key distribution with detection-efficiency mismatch in the multiphoton case [0.0]
  Current security of QKD with detection-efficiency mismatch rely on the assumption of the single-photon light source on the sender side or on the assumption of the single-photon input of the receiver side. Here we present a rigorous security proof without these assumptions and, thus, solve this important problem and prove the security of QKD with detection-efficiency mismatch against general attacks.
