DecoherenceStrategy
plain-language theorem explainer
DecoherenceStrategy enumerates five discrete tactics for keeping a quantum system below the Gap-45 threshold and thereby extending coherence time. A researcher deriving RS-based error-correction bounds would cite the type when mapping environment parameters to mitigation choices. The declaration is a bare inductive type whose constructors carry no proof obligations.
Claim. Inductive type whose constructors are the five decoherence-mitigation strategies: reduce coupling strength $g$, reduce number of environmental modes $N$, apply active error correction, apply dynamical decoupling pulse sequences, and invoke topological qubit protection.
background
The QFT.Decoherence module treats Gap-45 as the threshold separating coherent superposition from environmental entanglement. Decoherence time is expressed as $τ_{decoherence} ≈ τ_0 φ^{-N}$, where $N$ counts coupled modes and $φ$ is the golden-ratio scaling factor supplied by the forcing chain. The upstream structure for from UniversalForcingSelfReference records the meta-realization axioms that justify treating these strategies as discrete, exhaustive choices within the self-referential orbit.
proof idea
The declaration is an inductive definition that simply enumerates the five named constructors with no further structure or proof obligations.
why it matters
The type supplies the domain for the downstream strategyImprovement function, which assigns concrete improvement factors ranging from 10 to 10^6. It directly implements the QF-009 program of deriving decoherence timescales from the Gap-45 boundary and the eight-tick octave of the Recognition Science forcing chain. No open scaffolding is attached.
