Crypto-nonlocality in arbitrarily dimensional systems
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
According to Bell's theorem, any model based on local variables cannot reproduce certain quantum correlations. A critical question is whether one could devise an alternative framew…
Orbital Angular Momentum Experimental Bound on the Maximum Predictive Power of Physical Theories in Multi-Dimensional Systems
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
The completeness of quantum mechanics in predictive power is a central question in its foundational study. While most investigations focus on two-dimensional systems, high-dimensio…
Coherent generation of the complete high-dimensional Bell basis by adaptive pump modulation
Yuanyuan Chen, Wuhong Zhang, Dongkai Zhang +2
The Bell basis, a set of maximally entangled biphoton state, is a critical prerequisite towards quantum information processing, and many quantum applications have highlighted the r…
Orbital-angular-momentum-based experimental test of Hardy's paradox for multisetting and multidimensional systems
Dongkai Zhang, Xiaodong Qiu, Tianlong Ma +2
Characterizing high-dimensional entangled states is of crucial importance in quantum information science and technology. Recent theoretical progress has been made to extend the Har…
Quantum remote sensing of angular rotation of structured objects
Wuhong Zhang, Dongkai Zhang, Xiaodong Qiu +1
Based on two-photon entanglement, quantum remote sensing enables the measurement and detection to be done non-locally and remotely. However, little attention has been paid to imple…
Free-space remote sensing of rotation at photon-counting level
Wuhong Zhang, Jingsong Gao, Dongkai Zhang +4
The rotational Doppler effect associated with light's orbital angular momentum (OAM) has been found as a powerful tool to detect rotating bodies. However, this method was only demo…
