La Profilée - Quantum Identity: La Profilée and the Structural Conditions of Persistence in Quantum Systems

Classical theories of identity presuppose that a system’s states are distinguishable over time. Quantum mechanics appears to challenge this: individual quantum constituents are not distinguishable in the classical sense, and systems in superposition do not occupy definite configurations. The present paper establishes that La Profilée’s structural persistence condition IR = R / (F · I · C) ≤ 1 is compatible with quantum mechanics and illuminated by it. LP does not require distinguishability of constituents. It requires distinguishability of states — a condition satisfied in quantum mechanics at the level of system states, not individual particles. Superposition corresponds structurally to a regime in which transformation has not yet been integrated: no stable, distinguishable configuration persists at the level of specific outcomes. Measurement is not an epistemic act but a physical coupling process that increases integration capacity through decoherence, driving IR below 1 and enabling a persistent configuration to emerge. The paper derives the structural correspondence: decoherence rate corresponds to R, environmental coupling strength to C, and the system’s capacity to maintain correlated states with its environment to I. Quantum mechanics does not contradict LP’s persistence condition. It illustrates its relevance at the most fundamental physical level: identity is not a primitive property of matter. It is the structural result of sufficient integration.
