Violation of Heisenberg’s Error-Disturbance Relation by Stern-Gerlach Measurements. (arXiv:2009.01646v1 [quant-ph]) 上午10:15 | Yuki Inoue, Masanao Ozawa | quant-ph updates on arXiv.org Although “Heisenberg’s uncertainty principle” is represented by a rigorously proven relation about intrinsic indeterminacy in quantum states, Heisenberg’s error-disturbance relation (EDR) has been commonly believed as another aspect of the principle. However, recent developments of quantum measurement theory made… Read more →

Meaning relativism and subjective idealism 上午8:00 | Latest Results for Synthese Abstract The paper discusses an objection, put forward by—among others—John McDowell, to Kripke’s Wittgenstein’s non-factualist and relativist view of semantic discourse. The objection goes roughly as follows: while it is usually possible to be a relativist about a given domain of discourse without being a relativist about anything else,… Read more →

How to switch between relational quantum clocks. (arXiv:1810.04153v2 [gr-qc] UPDATED) 上午9:37 | gr-qc updates on arXiv.org Authors: Philipp A Hoehn, Augustin Vanrietvelde Every clock is a physical system and thereby ultimately quantum. A naturally arising question is how to describe time evolution relative to quantum clocks and, specifically, how the dynamics relative to different quantum clocks are related. This is a pressing… Read more →

The Connection between Bohmian Mechanics and Many-Particle Quantum Hydrodynamics 上午8:00 | Latest Results for Foundations of Physics Abstract Bohm developed the Bohmian mechanics (BM), in which the Schrödinger equation is transformed into two differential equations: a continuity equation and an equation of motion similar to the Newtonian equation of motion. This transformation can be executed both for single-particle systems and… Read more →

Observations of coherence de Broglie waves. (arXiv:2007.04738v1 [quant-ph]) 上午10:12 | Byoung S. Ham | quant-ph updates on arXiv.org Photonic de Broglie waves (PBWs) via two-mode entangled photon pair interactions on a beam splitter show a pure quantum feature which cannot be obtained by classical means1-4. Although PBWs have been intensively studied for quantum metrology5-13 and quantum sensing14-25 over the last… Read more →

The appearance of particle tracks in detectors. (arXiv:2007.00785v1 [math-ph]) 上午9:14 | Miguel Ballesteros, Tristan Benoist, Martin Fraas, Jürg Fröhlich | quant-ph updates on arXiv.org The phenomenon that a quantum particle propagating in a detector, such as a Wilson cloud chamber, leaves a track close to a classical trajectory is analyzed. We introduce an idealized quantum-mechanical model of a charged particle… Read more →

Born’s rule from almost nothing. (arXiv:2006.14175v1 [quant-ph]) 上午10:14 | Sabine Hossenfelder | quant-ph updates on arXiv.org We here put forward a simple argument for Born’s rule based on the requirement that the probability distribution should not be a function of the number of degrees of freedom. How small an environment can be to still generate decoherence?. (arXiv:2006.14468v1 [quant-ph]) 上午10:14 |… Read more →

The CHSH Test Can be Used for All Quantum-Describable Systems 上午8:00 | Latest Results for Foundations of Physics Abstract This paper shows that the Clauser–Horne–Shimony–Holt test of locality of correlations which was originally designed to be used with binary observables can actually be used for any couples of quantum-like bounded continuous observables, and then for any experimental situation describable within… Read more →
