Witnessing the survival of time-energy entanglement through biological tissue and scattering media. (arXiv:2102.12907v1 [quant-ph]) 上午10:17 | Daniel J. Lum, Michael D. Mazurek, Alexander Mikhaylov, Kristen M. Parzuchowski, Ryan N. Wilson, Ralph Jimenez, Thomas Gerrits, Martin J. Stevens, Marcus T. Cicerone, Charles H. Camp Jr | quant-ph updates on arXiv.org We demonstrate the preservation of time-energy entanglement of near-IR photons through… 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 →

Approaches to causality and multi-agent paradoxes in non-classical theories. (arXiv:2102.02393v1 [quant-ph]) 上午10:10 | V. Vilasini | quant-ph updates on arXiv.org This thesis reports progress in the analysis of causality and multi-agent logical paradoxes in quantum and post-quantum theories. These research areas are highly relevant for the foundations of physics as well as the development of quantum technologies. In the first… 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 →

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 →
