Aspects of wave-particle complementarity in quantum delayed-choice experiments

Abstract Quantum delayed-choice experiments are designed to probe the robustness of complementarity principle. In this proceeding, we revisit main ideas reported recently in Ref. [Commun. Phys. 5, 82 (2022)] concerning a setup (quantum-controlled reality experiment) that has same final visibility as quantum version Wheeler’s arrangement. Besides statistics, upon an operational criterion physical realism, authors claimed different state affairs for wave-and-particle behavior experiments. To end, put forward analysis by employing relative entropy coherence study how local wave and particle coherences when system is traveling inside interferometer change accordingly observed visibility.
