I apologize if my previous response was unclear. The entanglement of particles does not enable them to communicate with each other instantly or faster than the speed of light.
When two particles become entangled, their quantum states become correlated in a way that measuring one particle's state will instantaneously determine the state of the other, regardless of the spatial separation between them. This instantaneous correlation might appear to suggest faster-than-light communication or "instantaneous" interaction between the particles.
However, it is important to note that entanglement does not allow for the transmission of information or messages in a conventional sense. The measurement outcomes of entangled particles appear random and do not convey any meaningful information until a classical communication channel is established between the observers who have measured the entangled particles. This classical communication, limited by the speed of light, is necessary to compare measurement results and find correlations.
The apparent faster-than-light behavior in entanglement experiments is a consequence of the non-local nature of quantum mechanics. It means that the quantum state of an entangled system cannot be described by individual states of the constituent particles but requires a joint description. However, this non-locality does not allow for the transmission of information or communication faster than light.
The no-communication theorem, proposed by physicists like John Bell and proven through various experiments, states that it is impossible to use entanglement to transmit information faster than the speed of light. The correlations observed in entangled particles are inherent properties of the quantum system and cannot be exploited for communication purposes.
