Paper 43 — Generative Law: Quantum Decoherence as Law Leakage

Decoherence is commonly described as the gradual loss of quantum behavior due to interaction with an environment. This description, while operationally useful, obscures the structural origin of the phenomenon. It treats decoherence as a dynamical process acting on states rather than as a failure in maintaining admissibility constraints. This paper reframes decoherence as law leakage: the breakdown of isolation that defines a law-domain. Within the Generative Law framework, coherence is not a property of states but a condition of constraint purity. Decoherence occurs when external admissibility structures intrude upon a restricted law-domain, contaminating its constraint boundaries. Under this interpretation, the environment is not a physical agent that “measures” or “disturbs” a system, but a reservoir of incompatible laws. Decoherence reflects the inability to prevent cross-law coupling as complexity increases. By treating decoherence as leakage rather than noise, this work dissolves probabilistic and thermodynamic narratives that obscure mechanism. It positions decoherence as an engineering limitation on law construction, directly complementary to entanglement as law engineering. This article is part of a broader theoretical program investigating the emergence of spacetime, geometry, and physical structure from the ψ–Θ–χ continuum.
