QCMT‑SC v1.0: A Quantum Coherence Mass Test Using Superconducting Phase Transitions

QCMT‑SC v1.0 presents a complete, experimentally testable protocol for measuring whether macroscopic quantum coherence contributes to gravitational mass. The experiment compares the gravitational mass of a high‑purity niobium sample in two coherence states: - Normal metallic state (ICS = 0) - Superconducting state (ICS ≈ 1) Using precision gravimetry under controlled cryogenic conditions, the protocol isolates coherence‑dependent mass contributions while suppressing thermal, magnetic, buoyancy, and mechanical systematics. The document includes: - theoretical background (CCEC framework and Informational Coherence State), - full sample specification, - cryogenic and magnetic shielding requirements, - gravimeter…
