The notion that Bell inequality violations prove nonlocality in nature is being reevaluated, with the conclusion that this claim is not necessarily supported by either the Einstein-Podolsky-Rosen argument or Bell's theorem1. A key aspect of this reassessment is the role of counterfactual reasoning, which assumes that unperformed measurements have definite outcomes. This challenge to the prevailing view on nonlocality has significant implications for the foundations of quantum mechanics. The EPR-Bell argument, long considered a cornerstone of quantum nonlocality, is found to be more nuanced than previously thought. As quantum advancements, particularly in decentralized finance, continue to reshape the landscape of computation and cryptography, this reexamination of nonlocality could have far-reaching consequences. So what matters to practitioners is that this newfound understanding of nonlocality may ultimately influence the development of quantum-resistant cryptographic protocols and timelines.
