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 →
The kh{\^o}ra and the two-triangle universe of Plato’s Timaeus. (arXiv:2008.11947v1 [math.HO]) 上午8:56 | physics.hist-ph updates on arXiv.org Authors: Luc Brisson, Salomon Ofman (IMJ-PRG (UMR\_7586)) The main purpose of this article is to try to understand the connection between the physical universe and the mathematical principles that underlies the cosmological account of the Timaeus. Aristotle’s common criticism of Plato’s cosmology is that he confuses… 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 →
