AWhat changed
For translation-invariant finite-range interactions on a quantum spin lattice with finite-dimensional site spaces, the norm of a commutator between separated local observables becomes exponentially small outside a sufficiently fast space-time cone. The proof bounds dynamical influence independently of the chosen quantum state.
Scientific scope
For translation-invariant finite-range interactions on a quantum spin lattice with finite-dimensional site spaces, the norm of a commutator between separated local observables becomes exponentially small outside a sufficiently fast space-time cone. The proof bounds dynamical influence independently of the chosen quantum state. This is an exponentially suppressed tail, not exact relativistic causality or a theorem for arbitrary long-range and unbounded interactions. The finite velocity bound need not be sharp. The paper remarks on exponentially decaying extensions, but the core staged claim uses its explicit finite-range hypotheses.
Evidence
The linked original works support the scoped statement and contribution attribution. WRS has not independently replayed experiments or reconstructed a full mathematical proof. This is an exponentially suppressed tail, not exact relativistic causality or a theorem for arbitrary long-range and unbounded interactions. The finite velocity bound need not be sharp.
