Physics as Information: Quantum Theory meets Relativity Speaker(s): Giacomo D'Ariano
Abstract: I will review some recent advances on the line of deriving quantum field theory from pure quantum information processing. The general idea is that there is only Quantum Theory (without quantization rules), and the whole Physicsincluding spacetime and relativityis emergent from the processing. And, since Quantum Theory itself is made with purely informational principles, the whole Physics must be reformulated in informationtheoretical terms. Here's the TOC of the talk: a) Very short review of the informational axiomatization of Quantum Theory; b) How spacetime and relativistic covariance emerge from the quantum computation; c) Special relativity without space: other ideas; d) Dirac equation derived as information flow (without the need of Lorentz covariance); e) Informationtheoretical meaning of inertial mass and Planck constant; f) Observable consequences (at the Planck scale?); h) What about Gravity? Three alternatives as a start for a brainstorming.
