expEPR

expEPR is a term used in quantum physics to denote experimental investigations of the Einstein–Podolsky–Rosen (EPR) paradox and the phenomenon of quantum nonlocality. The exact meaning of expEPR varies by author, but it generally refers to experiments designed to observe or verify entanglement and the correlations predicted by quantum mechanics, as opposed to purely theoretical discussions of the EPR argument. In practice, expEPR studies are conducted across platforms such as photonic systems, trapped ions, superconducting qubits, and other solid‑state qubits, where researchers perform Bell tests or related measurements to probe nonlocal correlations. The term is common in certain review articles, conference reports, and project descriptions that emphasize experimental verification of EPR-related effects. While expEPR is not a single standardized program, it serves as a label for research aimed at elucidating foundational questions about locality, realism, and the completeness of quantum mechanics, as well as for advancing practical quantum information tasks that rely on entanglement. Related topics include the original EPR paradox, Bell's theorem, and quantum entanglement. See also: EPR paradox, Bell's theorem, quantum entanglement.
