The Spacelike Associator Paradox: Sequential Quantum Channels, Non-Associative Measurement Back-Action, and the Causal Firewall of the G₂ Vacuum
| Paper: 268 | Portfolio F — Quantum Foundations |
Abstract
Three spacelike-separated CPTP channels exhibit a non-zero composition associator (Frobenius distance 0.2134) for non-Fano triples and zero associator on Fano lines. The G₂ vacuum acts as a causal firewall.
