Quantum entanglement -- “spooky action at a distance” -- links the properties of particles even when they are separated by large distances. When a property of one of a pair of entangled particles is measured, the other “immediately” settles down into a state compatible with that measurement.
So how fast is “immediately”? ... the lower limit to the speed associated with entanglement dynamics is at least 10,000 times faster than light.
