Hensen and colleagues: an event-ready loophole-free Bell test

What changed

A single experiment tested local-realist constraints without the major locality and detection loopholes.

Scientific scope

Nineteen-author 2015 experiment; Bell's theorem, prior tests and later replications separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 2015 Nature paper and its 245-trial statistical result. Bell’s theorem, Aspect’s earlier tests, simultaneous photonic experiments, later replications and device-independent applications remain separate.
