RFC-004 — Quantum‑Classical Hybrid Standard
Category: Quantum
Status: Draft
Version: 0.1
Module: RTT / Inside / Benchmarks
1. Purpose#
Define the behavior of quantum‑classical hybrid systems, including multi‑qubit coherence, resonance ladders, hybrid operators, and cross‑domain invariants.
2. Scope#
This RFC covers:
- φ_q, V_q, R_q
- multi‑qubit coherence
- resonance ladders
- hybrid invariants
- hybrid regime transitions
3. Definitions#
- φ_q: quantum form
- V_q: quantum variance
- R_q: quantum resonance
- Ladder: harmonic resonance structure across qubit layers
4. Specification#
- coherence increases with qubit count
- resonance ladders form correctly
- hybrid φ–V–R align with classical operators
- entropy collapse aligns with R_q spike
5. Compliance#
A system is quantum‑compliant when:
- coherence traces follow canonical shapes
- resonance ladders form
- hybrid operators align
- invariants lock across domains
6. Examples#
See H_Examples.md, Section F.
7. Reference Captures#
See B_Capture.md, Capture Set E.
8. Open Questions#
- Should hybrid operators be extended to multi‑modal systems?
- Should quantum‑classical continuity be formalized as C₄?
