As far as we know entanglement acts instantly. To summarize the result. Chinese researchers set a low limit for the speed of quantum entanglement to be about 10,000 times the speed of light. There is no upper limit as far as we know.
>Of course, this violates relativity in the sense that nothing can travel faster than light.
No it does not. As long as only correlation is instant, there is no limit for the speed. Causality travels at the speed of light at maximum as usual.
>Even then, a ton of work is being done in this field and a growing number of physicists believe we’ll achieve faster-than-light communication by cleverly using quantum entanglement to our advantage.
