Bell test experiments

Bell test experiments investigate whether nature follows classical ideas of local realism (objects have definite states and no influence travels faster than light) or if quantum mechanics’ predictions of entanglement hold true. In these tests, pairs of entangled particles are created and sent to separate detectors, which measure their properties independently. The results show correlations that can’t be explained by any local hidden variables, confirming quantum entanglement. This demonstrates that particles can be connected in a way that instantaneously influences one another, regardless of distance, challenging classical notions of separability and locality.
