“…The realism measure gives a prominent role to the notion of information and can be applied in several different contexts [14,16,17,18,19,20,21,22,23,24]. For instance, by employing a model of measurement called monitoring [14,25], which consists of interpolating weak and strong non-selective measurements, it was possible to deduce a formal connection between information and the concept of reality for quantum states, exhibiting a dual relationship for both quantities coined as Information-reality complementarity [14].…”

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

“…[18], as well as realism-based nonlocality was explored in Refs. [19,20,21,22]. Realism was discussed in the context of random quantum walk [23], Hardy's paradox [24], generalized resource theory of information [27], and more recently, to analyze the Aharonov-Bohm effect [28].…”
