Stefan Wolf de l’Université de Lugano, Pinchat, Seminar room, 4:15pm Landauer's principle claims that "Information is Physical." A flavor of its conceptual antipode, Wheeler's "It from Bit," is the Church/Turing thesis: All natural processes can be computed by a universal Turing machine. Physical laws then become descriptions of subsets of actually observable, as opposed to merely possible, computations. Bell correlations imply a separation: Either beyond-Turing computations are impossible in nature, or they can be carried out even by single photons.
