Operational Theories in Phase Space: Toy Model for the Harmonic Oscillator. (arXiv:2101.08323v1 [quant-ph]) 上午9:07 | Martin Plávala, Matthias Kleinmann | quant-ph updates on arXiv.org We construct a toy model for the harmonic oscillator that is neither classical nor quantum. The model features a discrete energy spectrum, a ground state with sharp position and momentum, an eigenstate with non-positive Wigner function… Read more →
Nonlocality via Entanglement-Swapping — a Bridge Too Far?. (arXiv:2101.05370v1 [quant-ph]) 上午11:33 | Huw Price, Ken Wharton | quant-ph updates on arXiv.org A 2015 experiment by Hanson and his Delft colleagues provided new confirmation that the quantum world violates the Bell inequalities, closing some loopholes left open by previous experiments. The experiment was also taken to provide new evidence of quantum… Read more →
The hydrogen atom: consideration of the electron self-field. (arXiv:2101.02202v1 [quant-ph]) 上午9:31 | Leon V. Biguaa, Vladimir V. Kassandrov | quant-ph updates on arXiv.org We substantiate the need for account of the proper electromagnetic field of the electron in the canonical problem of hydrogen in relativistic quantum mechanics. From mathematical viewpoint, the goal is equivalent to determination of the spectrum of… Read more →
Intrinsic quantum coherence in particle oscillations. (arXiv:2012.14866v1 [hep-ph]) 上午8:59 | Anca Tureanu | quant-ph updates on arXiv.org The quantum field theoretical description of coherence in the oscillations of particles, especially neutrinos, is a standing problem in particle physics. In this talk, several inconsistencies of the standard approach to particle oscillations will be explained, and how they are resolved in a… Read more →

Nuclear clocks for testing fundamental physics. (arXiv:2012.09304v1 [quant-ph]) 上午10:22 | E. Peik, T. Schumm, M. S. Safronova, A. Pálffy, J. Weitenberg, P. G. Thirolf | quant-ph updates on arXiv.org The low-energy, long-lived isomer in $^{229}$Th, first studied in the 1970s as an exotic feature in nuclear physics, continues to inspire a multidisciplinary community of physicists. Using the nuclear resonance frequency,… Read more →
A no-go theorem for Quantum theory ontological models. (arXiv:2012.05712v1 [quant-ph]) 上午9:28 | Tung Ten Yong | quant-ph updates on arXiv.org In this paper, we show that Quantum Mechanics does not admit ontological models, in the sense that the quantum state of a system cannot correspond to a set of physical states representing the independent reality of the system. We show,… Read more →

Predictability, Distinguishability and Entanglement. (arXiv:2011.08210v1 [quant-ph]) 上午8:59 | Tabish Qureshi | quant-ph updates on arXiv.org Recent times have seen a spurt of research activity focused on “completing” certain wave-particle duality relations using entanglement or polarization. These studies use a duality relation involving path-predictability, and not path-distinguishability. Quantum origins of these results are explored here, in the more general framework of… Read more →
Objective trajectories in hybrid classical-quantum dynamics. (arXiv:2011.06009v1 [quant-ph]) 上午9:32 | Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda, Zachary Weller-Davies | quant-ph updates on arXiv.org Consistent dynamics which couples classical and quantum degrees of freedom exists, provided it is stochastic. This provides a way to study the back-reaction of quantum fields on space-time which does not suffer from the pathologies of the… Read more →
