Deciphering quantum enigmas: The role of nonlocal boxes in defining the boundaries of physical feasibility

A team of scientists from the University of Ottawa is offering insights into the mysteries of quantum entanglement. Their recent study, titled “Extending the known region of nonlocal boxes that collapse communication complexity” and published in Physical Review Letters (PRL), discloses that various theoretical quantum theory extensions are considered non-physical when tested against the principle of non-trivial communication complexity.
