At what time does a quantum experiment have a result?   The Extended Bloch Representation of Quantum Mechanics for Infinite-Dimensional Entities. (arXiv:1704.06249v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-4-21 7:39am GMT Authors: Diederik Aerts, Massimiliano Sassoli de Bianchi We show that the extended Bloch representation of quantum mechanics also applies to infinite-dimensional entities, to the extent that the number of (possibly infinitely...

Quantum detection of wormholes. (arXiv:1702.01720v2 [quant-ph] UPDATED)  gr-qc updates on arXiv.org on 2017-4-08 12:56am GMT Authors: Carlos Sabín We show how to use quantum metrology to detect a wormhole. A coherent state of the electromagnetic field experiences a phase shift with a slight dependence on the throat radius of a possible distant wormhole. We show that this tiny correction is, in...

Classical Branch Structure from Spatial Redundancy in a Many-Body Wave Function  PRL: General Physics: Statistical and Quantum Mechanics, Quantum Information, etc. on 2017-3-24 2:00pm GMT Author(s): C. Jess Riedel When the wave function of a large quantum system unitarily evolves away from a low-entropy initial state, there is strong circumstantial evidence it develops “branches”: a decomposition into orthogonal components that...

Quantum Probabilities as Behavioral Probabilities. (arXiv:1703.05691v1 [q-bio.NC])  quant-ph updates on arXiv.org on 2017-3-18 9:36am GMT Authors: V.I. Yukalov, D. Sornette We demonstrate that behavioral probabilities of human decision makers share many common features with quantum probabilities. This does not imply that humans are some quantum objects, but just shows that the mathematics of quantum theory is applicable to the description of human... Read more →

Weekly Papers on Quantum Foundations (10)

The unexpected resurgence of Weyl geometry in late 20-th century physics. (arXiv:1703.03187v1 [math.HO])  gr-qc updates on arXiv.org on 2017-3-11 7:48am GMT Authors: Erhard Scholz Weyl's original scale geometry of 1918 ("purely infinitesimal geometry") was withdrawn by its author from physical theorizing in the early 1920s. It had a comeback in the last third of the 20th century in different contexts: scalar... Read more →

Reversible time travel with freedom of choice. (arXiv:1703.00779v1 [gr-qc])  quant-ph updates on arXiv.org on 2017-3-04 8:42am GMT Authors: Ämin Baumeler, Fabio Costa, Timothy C. Ralph, Stefan Wolf, Magdalena Zych General relativity predicts the existence of closed time-like curves, along which a material object could travel back in time and interact with its past self. The natural question is whether this possibility leads to inconsistencies: Could... Read more →

Weekly Papers on Quantum Foundations (7)

Information content of systems as a physical principle  PRA: Fundamental concepts on 2017-2-17 3:00pm GMT Author(s): L. Czekaj, M. Horodecki, P. Horodecki, and R. Horodecki To explain the conceptual gap between classical and quantum and other, hypothetical descriptions of the world, several principles have been proposed. So far, all these principles have not explicitly included the uncertainty relation. Here we... Read more →
