Towards the Heisenberg limit in microwave photon detection by a qubit array. (arXiv:2009.11271v2 [quant-ph] UPDATED) 上午9:49 | P. Navez, A. G. Balanov, S. E. Savel’ev, A. M. Zagoskin | quant-ph updates on arXiv.org Using an analytically solvable model, we show that a qubit array-based detector allows to achieve the fundamental Heisenberg limit in detecting single photons. In case of superconducting… Read more →
Finding the world in the wave function: some strategies for solving the macro-object problem 上午8:00 | Latest Results for Synthese Abstract Realists wanting to capture the facts of quantum entanglement in a metaphysical interpretation find themselves faced with several options: to grant some species of fundamental nonseparability, adopt holism, or (more radically) to view localized spacetime systems as ultimately reducible… Read more →
Underground test of gravity-related wave function collapse 2020年9月7日 星期一 上午8:00 | Angelo Bassi | Nature Physics – Issue – nature.com science feeds Nature Physics, Published online: 07 September 2020; doi:10.1038/s41567-020-1008-4The radiation emission rate from gravity-related wave function collapse is calculated and the results of a dedicated experiment at the Gran Sasso laboratory are reported, ruling out the natural parameter-free version of… Read more →
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 →
