Summary:
- Quantum entanglement is a phenomenon in quantum physics where two or more particles become "entangled" and their properties become linked, even if they are separated by a large distance.
- This means that the state of one particle can instantly affect the state of the other, even if they are far apart, a concept that Einstein referred to as "spooky action at a distance."
- Experiments have shown that entangled particles can exhibit coordinated movement, where the movement of one particle is directly influenced by the movement of the other, providing evidence for the reality of quantum entanglement.
