Relational Quantum Mechanics
ORAL · Invited
Abstract
The relational interpretation of quantum mechanics (RQM) solves the measurement problem avoiding both hidden variables and many worlds, and yet remaining realistic, by considering an ontology of sparse relative events, instead than a quantum state ontology. Events are realized in interactions between any two physical systems and are relative to these systems. The relativity of the events can be neglected in the approximation where decoherence hides interference, thus making them (approximately) absolute. RQM is a refinement of the traditional "Copenhagen" views, that replaces the Copenhagen's classical observer with any arbitrary physical system.
