Quantum Physics arXiv:2605.07228 (quant-ph) [Submitted on 8 May 2026] Title:Kochen-Specker nonlocal hidden variables must include time-ordering to allow for measurement independence of several agents Authors:Valerio Scarani, Antoine Suarez View a PDF of the paper titled Kochen-Specker nonlocal hidden variables must include time-ordering to allow for measurement independence of several agents, by Valerio Scarani and Antoine Suarez View PDF HTML (experimental) Abstract:We consider an ontology, in which contextual nonlocal hidden variables are stored as pre-existing possibilities in a repository outside space-time; and in which the context can be chosen ``freely'' (measurement independence) by each agent, both in spacelike and timelike configurations. We show that, in Bell-type experiments involving several agents, for this ontology to be consistent, the context must include not only the measurements that can be performed, but also the time ordering of the choices of different agents.
