Macroscopicity of quantum mechanical superposition tests via hypothesis falsification. (arXiv:1902.11092v1 [quant-ph])  quant-ph updates on arXiv.org on 2019-3-02 12:26am GMT Authors: Björn Schrinski, Stefan Nimmrichter, Benjamin A. Stickler, Klaus Hornberger We establish an objective scheme to determine the macroscopicity of quantum mechanical superposition tests, which is based on the Bayesian hypothesis falsification of macrorealistic modifications of quantum theory. The measure uses the raw data gathered… Read more →

Outline for a quantum theory of gravity. (arXiv:1901.05953v1 [gr-qc])  hep-th updates on arXiv.org on 2019-1-19 7:38am GMT Authors: Tejinder P. Singh By invoking an asymmetric metric tensor, and borrowing ideas from non-commutative geometry, string theory, and trace dynamics, we propose an action function for quantum gravity. The action is proportional to the four dimensional non-commutative curvature scalar (which is torsion dependent)… Read more →
