"Nonlocal Boxes: Unveiling Quantum Entanglement's Boundaries"
A study published in Physical Review Letters by a team of scientists from the University of Ottawa explores the boundaries of quantum theory extensions by investigating nonlocal boxes and their relationship to non-trivial communication complexity. The research reveals that many theoretical generalizations of quantum theory represented by nonlocal boxes are considered non-physical when subjected to this postulate, providing valuable insights into the nature of quantum entanglement and the limitations of generalizing quantum mechanics. This work enhances our understanding of quantum theory limits and opens the door to progress in quantum information science.
