量子非定域性的概念是量子信息科学和技术的核心，在物理上是违反直觉的，在数学上是难以捉摸的。在这里，超纠缠辅助鬼成像系统的设计，通过捕捉纯粹的非局域光子事件与空间分辨增强电荷耦合器件（ICCD）相机的哈代的悖论的证据可视化。在哈代非定域性证明的逻辑结构中，在双光子偏振空间模超纠缠态中，空间纠缠传递鬼像，偏振纠缠编码成像通道.然后，是否观察到头骨形状物体的单个鬼像可以是支持或反对量子力学的直接而直观的签名。此外，局部性破坏的程度可以通过宏观上的鬼像的对比度-噪声比来表征，并且还实现了在单像素水平上微观上破坏局部性的非局部行为，具有75%的合理置信水平。所提出的策略不仅为量子力学的基本问题提供了新的视角，而且为开发基于超纠缠的量子成像技术带来了希望。
The concept of quantum nonlocality, lying at the heart of quantum information science and technologies, is physically counter‐intuitive and mathematically elusive. Here, a hyper‐entanglement‐assisted ghost imaging system is designed to visualize the evidence of Hardy's paradox by capturing the purely nonlocal photonic events with a spatially resolved intensified charge‐coupled device (ICCD) camera. In the two‐photon polarization‐spatial‐mode hyper‐entangled state, spatial entanglement conveys the ghost images while polarization entanglement encodes the imaging channels in the logical structure of Hardy's nonlocality proof. Then whether the single ghost image of a skull‐shape object is observed or not can be a direct yet intuitive signature to support or defy quantum mechanics. Moreover, the degree of the violation of locality can be characterized by the contrast‐to‐noise ratio of ghost images macroscopically, and the nonlocal behavior of violating the locality microscopically at the single‐pixel level with a reasonable confidence level of 75% is also achieved. The proposed strategy not only sheds new light on the fundamental issue of quantum mechanics, but also holds promise for developing hyper‐entanglement‐based quantum imaging technology.
