The No-Communication Theorem says superluminal quantum communication is impossible - but what if it's wrong?

In this presentation Dr. Kent Peacock discusses the no-communication theorem, also called the no-signalling principle, and explores fundamental logical flaws in this negative proof that may facilitate the future development of superluminal quantum communication.

In physics, the no-communication theorem or no-signaling principle is a no-go theorem from quantum information theory which states that, during measurement of an entangled quantum state, it is not possible for one observer, by making a measurement of a subsystem of the total state, to communicate information to another observer.

The theorem is important because, in quantum mechanics, quantum entanglement is an effect by which certain widely separated events can be correlated in ways that, at first glance, suggest the possibility of communication faster-than-light. The no-communication theorem gives conditions under which such transfer of information between two observers is impossible.

Dr. Peacock is a professor of philosophy at the University of Lethbridge, and is a philosopher of science focused on physics and ecology. He also has strong interests in the metaphysics of time, logic, environmental ethics, the nature of ingenuity and creativity, and the complex of challenges flowing out of humanity's current ecological crisis.
