Quantum Nonlocality: When Distance Doesn’t Matter

Quantum nonlocality means particles can be correlated instantly across vast distances.
It arises from entanglement, where measuring one particle affects the other.
This connection ignores classical limits, like the speed of light.
Einstein doubted it, calling it “spooky action at a distance.”
Bell’s Theorem provided a way to test whether nonlocality is real.
Countless experiments confirm nonlocal effects match quantum predictions.
Nonlocality doesn’t send usable signals faster than light—it preserves relativity.
It reveals reality is more interconnected than classical physics allows.
Nonlocal correlations underpin research in quantum communication and cryptography.
Quantum nonlocality shows that, at the deepest level, space and distance don’t define all relationships.
