Weekly Papers on Quantum Foundations (25)

Fixing extensions to General Relativity in the non-linear regime. (arXiv:1706.07421v1 [gr-qc])  hep-th updates on on 2017-6-24 7:39am GMT Authors: Juan Cayuso, Néstor Ortiz, Luis Lehner The question of what gravitational theory could supersede General Relativity has been central in theoretical physics for decades. Many disparate alternatives have been proposed motivated by cosmology, quantum gravity and phenomenological angles, and have been subjected to… Read more →

On testing the simulation hypothesis

Tom Campbell, Houman Owhadiy, Joe Sauvageauz, David Watkinson Can the hypothesis that reality is a simulation be tested? We investigate this question based on the assumption that if the system performing the simulation is fi nite (i.e. has limited resources), then to achieve low computational complexity, such a system would, as in a video game, render content (reality) only at the moment that information… Read more →

Quantum theory as a self-referential theory of inference. (arXiv:1705.04307v1 [quant-ph])  quant-ph updates on on 2017-5-13 3:42am GMT Authors: John Realpe-Gómez Here we derive the formalism of quantum theory from two intuitive principles: (i) inference is a physical process performed by physical systems, observers, which are part of the experimental setup— this implies non-commutativity; (ii) experiments must be described from a… Read more →
