Minimum Experimental Information for Certifying Bell Nonlocality of Gravity
Jianqi Sheng
A Bell violation by material probes certifies nonlocal behavior, but it does not identify which internal subsystem carried or was measured to produce that behavior. We determine th…
String-Monodromy Rigidity from Six-Point Consistency
Jianqi Sheng
Can the characteristic monodromy of string scattering be derived from S-matrix consistency alone, without assuming a worldsheet? We show that finite-particle consistency fixes it t…
Task-Dependent Syndrome Memory in Quantum Sensing and State Recovery
Jianqi Sheng
Preserving metrological information under noise is central to quantum sensing, yet finite detectors and memories impose an unavoidable limit on how finely noise trajectories can be…
Diffusive Speed Limits for U(1)-Covariant Quantum Error Correction
Jianqi Sheng
Fast preparation of quantum error-correcting codes is essential for scalable quantum memories, but geometric locality and charge conservation impose an unavoidable transport…
When Quantum States over Spacetime Have No Common Process
Jianqi Sheng
Determining whether observations across spacetime arise from one quantum process is central to causal inference and to consistent observer-relative descriptions. For quantum-state-…
Protecting Astronomical Interferometry through Quantum-Memory Scrambling
Jianqi Sheng
Preserving the complex visibility of coherently captured starlight is essential for quantum-assisted long-baseline interferometry, because this nonlocal coherence carries the spati…
Connecting Quantum Contextuality and Nonlocality
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
Quantum theory departs from classical physics in its treatment of correlations, most prominently through the phenomena of contextuality and nonlocality. Once regarded primarily as…
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…
Experimental Test of Quantum Nonlocality from Contextuality
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
There are two powerful arguments against the possibility of extending quantum mechanics, the violation of Bell inequalities and the Kochen-Specker theorem, but the connection betwe…
