Quantum seminar | 24 July 2025

In this talk, I will explain the concept of quantum nonlocality and outline how it can be tested experimentally. I will begin by reviewing two selected experiments—one using entangled photons and another employing superconducting qubits. Next, I will turn to neutral pseudoscalar mesons (kaons, B‑mesons, and D‑mesons), which can serve as qubits with unique properties. I will introduce Wigner inequalities and demonstrate how their violations could be observed in these meson systems, offering new pathways to probe the “spooky” connections predicted by quantum theory.
