Quantum mechanics via quantum tomography. (arXiv:2110.05294v3 [quant-ph] UPDATED) 上午9:51 | Arnold Neumaier | quant-ph updates on arXiv.org Starting from a new basic principle inspired by quantum tomography rather than from Born’s rule, this paper gives an elementary, and self-contained deductive approach to quantum mechanics and quantum measurement. A suggestive notion for what constitutes a quantum detector and for the behavior… Read more →

New about the wave function, ”Einstein’s Boxes” and scattering a particle on a 1D short-range potential

Published by on

I hope that these two new results presented in arXiv:1805.03952v12 will be interesting: I have found that the process of scattering a particle on a one-dimensional delta-potential (and any other short-range potential) is closely related to the thought experiment “Einstein’s Boxes”. I presented a new view on this experiment. The main feature of this view is that this experiment is… Read more →

The Relativity Principle at the Foundation of Quantum Mechanics. (arXiv:2107.06942v1 [quant-ph]) 下午5:48 | W.M. Stuckey, Timothy McDevitt, Michael Silberstein | quant-ph updates on arXiv.org Quantum information theorists have created axiomatic reconstructions of quantum mechanics (QM) that are very successful at identifying precisely what distinguishes quantum probability theory from classical and more general probability theories in terms of information-theoretic principles. Herein,… Read more →

Revisiting the compatibility problem between the gauge principle and the observability of the canonical orbital angular momentum in the Landau problem. (arXiv:2104.10885v1 [quant-ph]) 上午9:11 | M. Wakamatsu, Y. Kitadono, L.-P. Zou, P.-M. Zhang | quant-ph updates on arXiv.org As is widely-known, the eigen-functions of the Landau problem in the symmetric gauge are specified by two quantum numbers. The first is… Read more →

Observing a Topological Transition in Weak-Measurement-Induced Geometric Phases. (arXiv:2102.05660v1 [quant-ph]) 上午10:05 | Yunzhao Wang, Kyrylo Snizhko, Alessandro Romito, Yuval Gefen, Kater Murch | quant-ph updates on arXiv.org Measurement plays a quintessential role in the control of quantum systems. Beyond initialization and readout which pertain to projective measurements, weak measurements in particular, through their back-action on the system, may enable various… Read more →

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 →
