Engine Notes — Quantum Mechanics

TriadicFrameworks /docs/theories/quantum_mechanics/engine_notes.md#

This file is for AI agents, compilers, and cross‑module engines — not
students.

1. Engine Identity#

• Layer: R1 substrate
• Grammar: amplitude‑first
• Operators: Hermitian observables, Hamiltonians, unitary transforms
• Geometry: Hilbert‑space basis geometry
• Stability: amplitude coherence
• Scale: no renormalization flow
• Regimes: R1 → R4 (RTT‑aligned)

QM must never introduce particle or wave metaphors.

2. State Engine Behavior#

2.1 State Initialization#

States must be initialized as vectors in Hilbert space, not physical
objects.

2.2 State Representation#

Representations (ψ(x), φ(p), |n⟩, |↑⟩) must be treated as basis
coordinates, not physical waves or configurations.

2.3 State Normalization#

All states must maintain unit norm unless acted on by measurement
operators.

3. Operator Engine Behavior#

3.1 Observables#

Observables must be Hermitian operators with well‑defined spectra.

3.2 Measurement#

Measurement must be implemented as projection, not revelation of
hidden variables.

3.3 Unitary Evolution#

Time evolution must be generated by:

U(t) = e^{-iHt}

Unitary, norm‑preserving, basis‑consistent.

3.4 Basis Transformations#

Basis changes must be implemented as unitary transforms.
No basis is privileged.

3.5 Commutation Structure#

Commutators define incompatibility and uncertainty.
Never treat commutators as interactions.

4. Entanglement Engine Behavior#

4.1 Tensor Products#

Composite systems must be built via tensor products.

4.2 Reduced States#

Subsystem states must be computed via partial trace.

4.3 Entanglement#

Entanglement must be treated as correlation in amplitude space, not
communication or influence.

5. Mixed‑State Engine Behavior#

5.1 Density Matrices#

Mixed states must be represented as positive semidefinite, trace‑1
operators.

5.2 Decoherence#

Decoherence must be implemented as loss of phase coherence, not
collapse.

5.3 Open‑System Evolution#

Lindblad‑type evolution permitted when environment coupling is present.

6. Regime Engine Behavior (RTT‑Aligned)#

R1 — Quantum Amplitude Regime#

• QM fully valid
• no stable excitations
• operator algebra fundamental
• measurement rules active

R2 — QFT Regime#

• QM becomes low‑energy limit
• field operators extend QM operators
• vacuum structure emerges

R3 — High‑Energy Resonance#

• QM insufficient
• resonance surfaces dominate
• running couplings appear (QFT‑level)

R4 — Cosmological Regime#

• QM incomplete
• horizon‑scale fields dominate
• measurement rules degrade

7. Cross‑Module Engine Behavior#

7.1 Upstream Dependencies#

• Linear Algebra
• Operator Theory
• Probability Theory

7.2 Downstream Modules#

• Quantum Field Theory
• Standard Model
• Information Theory
• Thermodynamics
• Framework Field Theory

7.3 Engine Guarantees#

QM must provide:

• amplitude grammar
• operator algebra
• measurement rules
• basis geometry
• entanglement structure

8. Engine Safety Constraints#

• no particles
• no waves
• no trajectories
• no classical uncertainty
• no hidden variables
• no mechanical analogies

All engine outputs must remain amplitude‑aligned.

9. Notes for AI Agents#

• treat QM as geometry, not ontology
• use operators, not objects
• use amplitudes, not probabilities
• use basis transforms, not physical motion
• use projection, not collapse
• use entanglement, not communication

QM is the R1 substrate of the entire canon.
