A Limitless World

  Thinking about the velocity of light: The prospect of faster-than-light (FTL) communications revolves around quantum entanglement, a phenomenon Einstein described as “spooky action at a distance”. The idea is that entanglement implies instant communication. However, even though entangled quantum particles seem to interact with each other instantaneously -regardless of the distance, breaking the speed of light – with our current understanding of quantum mechanics, it is impossible to send data using quantum entanglement. That’s the key: the inability to send data or information. In order to “communicate,” you need to be able to send data. Bottom line: Quantum communication is not instantaneous.
