Superposition to Measurements: A Matter-Antimatter Interpretation of Quantum Collapse

We propose that quantum superposition corresponds to an unstable coexistence of matter and antimatter components within a single quantum state. Measurement, or environmental decoherence, annihilates the antimatter component, leaving a pure matter eigenstate. This framework predicts that pure antimatter systems cannot exhibit sustained matter-wave interference. HypothesisA generic quantum state is written:|ψ⟩ = α|m⟩ + β|a⟩where |m⟩ is the matter component, |a⟩ the antimatter component, and |α|² + |β|² = 1. Testable PredictionAntimatter systems will not display matter-wave interference. Antihydrogen subjected to a double-slit or grating interferometer will produce no interference fringes. Visibility V → 0 for all experimentally accessible timescales. Suggested TestsALPHA, GBAR, or AEGIS experiments at CERN: matter-wave interferometry with antihydrogen or positrons.
