# Quantum Substrate Model (QSM)

The Quantum Substrate Model (QSM) defines a structured extension of substrate‑level modeling in which regime structure, dimensional constraints, and interaction domains are explicitly declared.

Building on the principles established by the Boson Substrate Model (BSM), the QSM formalizes how multiple substrate regimes may coexist, transition, or interact without embedding empirical claims, physical interpretation, or domain‑specific semantics.

---

## Scope

The QSM is:
- Structural rather than empirical
- Concerned with regime organization and dimensional structure
- Architecture‑agnostic
- Compatible with layered modeling approaches

The QSM is not:
- A physical quantum theory
- A simulation or numerical framework
- An optimization or learning model
- A replacement for existing theoretical systems

---

## Relationship to BSM

The Quantum Substrate Model extends the Boson Substrate Model by introducing explicit regime structure and dimensional organization while preserving substrate neutrality.

BSM defines a minimal substrate layer with declared operating regimes.  
QSM formalizes how multiple such regimes may be structured, related, and bounded.

Adoption of QSM does not require modification of BSM or higher‑level models.

## Intended Use

The QSM is intended to support reasoning about structured substrate regimes beneath higher‑level models. It enables explicit declaration of regime boundaries, transitions, and dimensional constraints while preserving semantic independence at higher layers.
