While entangled particles share states instantly, no information is transmitted faster than light. Quantum entanglement is a strange and fascinating phenomenon in which two or more particles become linked, meaning that changes to one particle instantly affect the other, no matter how far apart they are. This has led some to wonder whether entanglement could be used for faster-than-light communication.
However, while entangled particles appear to influence each other instantly, they cannot be used to send usable information faster than light. This is because the outcome of measuring an entangled particle is random, and the person on the other end cannot control what result they will get. To compare results and confirm entanglement, scientists still have to send regular information using traditional methods, which are limited by the speed of light.
In other words, quantum entanglement is a connection that exists outside of space and time, but it does not allow messages or data to be transmitted faster than light. Physicists continue to study entanglement for its potential in quantum computing and encryption, but as of now, it does not provide a way to break the speed limit of the universe.
