Quantum entanglement disproves the principle of locality
Is it true that quantum entanglement disproves the principle of locality?
Yes. Quantum entanglement leads to the violation of Bell's inequalities, confirming that physical theories cannot simultaneously satisfy both quantum mechanics and local realism.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The retrieved literature consistently supports the standard quantum mechanical consensus that entanglement violates Bell inequalities, thereby ruling out local hidden variable theories (local realism). While some theoretical papers (e.g., [4]) debate the metaphysical interpretations of 'nonlocality' or attempt contextual reformulations, the core empirical fact remains that local realism is disproven by the violation of Bell inequalities. Papers [9] and [11] explicitly demonstrate these violations and the failure of local realism.
