Entangled particles do not communicate information instantaneously across space. Instead, when particles become entangled, their quantum states become correlated in a way that the outcome of a measurement on one particle is correlated with the outcome of a measurement on the other particle. This correlation holds regardless of the distance between the particles.
When entangled particles are measured, their correlated properties are revealed. However, this measurement outcome is probabilistic in nature. Until a measurement is made on one of the entangled particles, their states are described by a superposition of possible values. The act of measuring one particle collapses its wavefunction, determining the outcome of the measurement, and instantaneously affects the state of the other particle due to their entangled relationship.
This correlation does not involve the transfer of information or influence at speeds faster than light. The principle that information cannot be transmitted faster than the speed of light is known as the no-communication theorem. It ensures that causality and the relativistic framework of physics are preserved.
To emphasize, entangled particles do not enable communication in the traditional sense. The entanglement itself is established during a previous interaction or process, and subsequent measurements on the entangled particles reveal the correlated outcomes but do not provide a means for instantaneous communication or transfer of information.
