Quantum entanglement does not allow for faster-than-light communication or the transmission of information. While it is true that measurements or operations performed on one entangled particle can instantaneously affect the state of the other entangled particles, this does not violate the principle of causality or enable superluminal communication.
When two particles become entangled, their quantum states become correlated in a way that measuring one particle will instantaneously determine the outcome of certain measurements on the other particle, regardless of the distance between them. However, this correlation does not allow for the transmission of classical information faster than the speed of light.
The reason for this limitation is that the actual information transfer in quantum entanglement occurs when measurements are compared or information is extracted from the entangled particles. To gain information about the entangled system, one must bring the particles together and perform measurements on both of them, which requires physical interaction and the exchange of signals. This process is subject to the usual constraints of the speed of light and cannot be used for superluminal communication.
In summary, while quantum entanglement exhibits non-local correlations, it does not violate the principle of causality or enable faster-than-light communication. The speed of light remains the ultimate speed limit for the transfer of classical information in the universe, as dictated by the theory of relativity.
