"The universe has been computing since the Big Bang. Every particle interaction is a logic gate. What we call physical law is the universe's program. And if reality is computation, then coordination — entanglement — is not a feature. It is the source code."
MIT mechanical engineer who made the audacious argument that the universe is a quantum computer and has been running a program since the first moment of time. His book 'Programming the Universe' established that physical processes are equivalent to computational processes, and that information is not a description of matter — it is matter. He designed early practical quantum error-correcting codes and demonstrated quantum random walks as a universal computational primitive.
