Exploring the Local Orthogonality Principle

Understand

Nonlocality is arguably one of the most fundamental and counterintuitive aspects of quantum theory.

• Nonlocal correlations could, however, be even more nonlocal than quantum theory allows, while still complying with basic physical principles such as no-signaling.
• So why is quantum mechanics not as nonlocal as it could be? Are there other physical or information-theoretic principles which prohibit this? So far, the proposed answers to this question have been only partially successful, partly because they are lacking genuinely multipartite formulations.
