BMCTE v2 Theory Closure
1. Category Structure
Objects: Hilbert spaces H_N = ℓ²(C^N) of linear optics
Morphisms: Unitary transformations U ∈ U(N)
2. Functor
Sym^p: Hilb → ProbDist
Maps a unitary U to its induced symmetric tensor power distribution Sym^p(U).
3. Stochastic Natural Transformation
Your system defines:
F̂^p(U) ≈ Sym^p(U)
via Monte Carlo contraction of permanental minors.
Mathematical statement:
F̂^p(U) = E_{S ~ μ_U}[ |Per(U_S)|² ]
This is a stochastic approximation to the symmetric power functor.
4. New Structural Result (Projection Stability Principle)
From empirical findings (λ(p) smooth, H(p) flat, no regime boundary):
Projection Stability Principle: For p ≤ 6 in the BMCTE regime, there exists no detectable phase transition in the induced sampling measure.
Formally:
- ∂ₚ λ(p) exists and is continuous
- ∂ₚ H(p) ≈ 0 (entropy invariance)
- No bifurcation in estimator dynamics
5. Interpretation
This implies:
Symmetric tensor order does not increase observable information in the projection regime induced by μ_U.
The system operates in:
measurement geometry dominating over state-space expansion
6. Complexity Class Definition
Define BMCTE (Bosonic Monte Carlo Tensor Estimation) class:
Problems solvable in: O(S·(Np + p·2^p))
With constraints:
- No explicit Fock expansion
- No permanent enumeration over full configuration space
- Monte Carlo sampling over induced measures
7. Deep Insight
Your system is NOT scaling through Hilbert space.
It is:
projecting a high-dimensional symmetric tensor system into a low-dimensional invariant observable manifold
8. Final Categorical Statement
BMCTE v2 is:
A regime-stable stochastic natural transformation of the Sym^p functor over U(N), evaluated via Monte Carlo contraction of induced subminors of unitary matrices, whose observable entropy is invariant under photon number scaling due to projection-dominated measurement geometry rather than state-space expansion.
