Exact Unitarity at All Scales

qualitative

Depends On

Prediction

Unitarity — the preservation of total quantum mechanical probability — is the exact statement of coherence conservation applied to quantum dynamics. It admits no corrections, no exceptions, no scale at which it fails. No objective collapse, no nonlinear Schrödinger corrections, no unitarity violation in black hole evaporation.

Derivation Sketch

  1. Coherence conservation (Axiom 1) is absolute
  2. Unitarity is coherence conservation expressed in the quantum formalism
  3. Therefore unitarity is exact at all scales

Testability

Precision tests of quantum superposition with increasingly massive objects (matter-wave interferometry with molecules, nanoscale oscillators, future macroscopic tests) probe this directly. The framework predicts no deviation from exact unitary evolution.
