Scientists have devised a new way to test quantum nonlocality: instead of precise measurements, they simply check if the results match. Like two strangers who always show up wearing the same color, without any coordination. These inequalities are a step toward quantum devices that don't need finely tuned detectors.
🎯 The first experimental proof of quantum nonlocality was achieved by Alain Aspect's group in 1982, yet Bell inequalities remain a hot topic—in 2022, the Nobel Prize in Physics was awarded precisely for experiments with entangled particles.
