TL;DR

This paper reports a direct, model-independent observation of quantum nonlocality using a novel mechanical detection method, potentially challenging Lorentz invariance and suggesting new physics beyond the Standard Model.

Contribution

It introduces a mechanical approach to observe quantum nonlocality directly, without relying on Bell's theorem or other theoretical models.

Findings

Mechanical detection of photon polarization states is feasible.

Observation suggests potential violation of Lorentz invariance.

Indicates possible new physics beyond current models.

Abstract

We investigate direct observation of quantum nonlocality without reference to theoretical models (including Bell theorem) except quantum mechanics, with a bipartite polarization-entangled state in which one photon immediately reduces into a circular-polarization (CP) state after its partner is detected in another CP state. Of essence is the mechanical detection of the CP state of a photon that carries angular momentum and exerts a torque on a half-wave plate whose mechanical motion is then varied. If implemented, the model-independent observation of quantum nonlocality violates Lorentz invariance in experiment and may indicate new fundamental physics beyond the Standard Model.
