Quantum locality

Quantum locality is the principle that objects are directly influenced only by their immediate surroundings and not by distant events, respecting the speed limit set by light. In quantum physics, particles can become entangled, meaning their states are linked regardless of distance. When one particle's state is measured, the other's state appears to change instantly, no matter how far apart. This phenomenon challenges classical ideas of locality, but it doesn’t allow faster-than-light communication. Overall, quantum locality suggests that while entangled particles exhibit instantaneous correlations, these do not enable influence or information transfer faster than light, maintaining consistency with relativity.
