Weekly Papers on Quantum Foundations (43)

Spontaneous decoherence as a result of randomness in the flow of time. (arXiv:2110.11343v1 [quant-ph]) 上午10:17 | L.I. Rozonoer | quant-ph updates on arXiv.org The hypothesis of the random flow of time is considered. To do this, the concepts of microscopic random time and macroscopic mean time, as well as random modular time are introduced. The possibilities of experimental verification of… Read more →

Characterizing quantum instruments: from non-demolition measurements to quantum error correction. (arXiv:2110.06954v1 [quant-ph]) 2021年10月16日 星期六 上午11:02 | Roman Stricker, Davide Vodola, Alexander Erhard, Lukas Postler, Michael Meth, Martin Ringbauer, Philipp Schindler, Rainer Blatt, Markus Müller, Thomas Monz | quant-ph updates on arXiv.org In quantum information processing quantum operations are often processed alongside measurements which result in classical data. Due to the… Read more →

Weekly Papers on Quantum Foundations (40)

Gravity-related collapse of the wave function and spontaneous heating: revisiting the experimental bounds. (arXiv:2109.14980v1 [quant-ph]) 上午9:47 | Andrea Vinante, Hendrik Ulbricht | quant-ph updates on arXiv.org The possibility that the collapse of the wave function in quantum mechanics is a real and ultimately connected to (classical) gravity has been debated for decades, with main contributions by Di\’osi and Penrose. In… Read more →

Objective consequentialism and the plurality of chances 上午8:00 | Latest Results for Synthese Abstract I claim that objective consequentialism (OC) faces a problem stemming from the existence in some situations of a plurality of chances relevant to the outcomes of an agent’s acts. I suggest that this phenomenon bears structural resemblance to the well-known Reference Class problem. I outline a… Read more →

Weekly Papers on Quantum Foundations (38)

On possible explanations for quantum contextuality. (arXiv:2109.07636v1 [quant-ph]) 上午9:32 | Alisson Tezzin | quant-ph updates on arXiv.org Recent research on quantum contextuality has been strongly centered on device-independent frameworks, such as the many graph approaches to contextuality and the celebrated sheaf-theoretical approach. Contextuality is described in these frameworks as a property of data only, making it possible to characterize and… Read more →

Parity-Time Symmetry via Time-Dependent non-Unitary Gauge Fields. (arXiv:2109.03846v1 [physics.class-ph]) 上午9:54 | Mario A. Quiroz-Juárez, Zachary A. Cochran, José L. Aragón, Yogesh N. Joglekar, Roberto de J. León-Montiel | quant-ph updates on arXiv.org Parity-Time (PT) symmetric systems have been widely recognized as fundamental building blocks for the development of novel, ultra-sensitive opto-electronic devices. However, arguably one of their major drawbacks is… Read more →

A historical review and Bibliometric analysis of research on Weak measurement research over the past decades based on Biblioshiny. (arXiv:2108.11375v1 [cs.DL]) 上午9:55 | Jing-Hui Huang, Xue-Ying Duan, Fei-Fan He, Guang-Jun Wang, Xiang-Yun Hu | quant-ph updates on arXiv.org Weak measurement has enabled fundamental studies in both experiment and theory of quantum measurement. Numerous researches have indicated that weak measurements have… Read more →

Conserved Quantities and Measurements. (arXiv:2108.08342v1 [quant-ph]) 2021年8月20日 星期五 下午3:42 | Edward J. Gillis | quant-ph updates on arXiv.org When a measurement is made on a system that is not in an eigenstate of the measured observable, it is often assumed that some conservation law has been violated. Discussions of the effect of measurements on conserved quantities often overlook the possibility… Read more →

Determination of finite dimensional pure quantum state by the discrete analogues of position and momentum. (arXiv:2108.05752v1 [quant-ph]) 上午9:21 | Yu Wang | quant-ph updates on arXiv.org The position and momentum distributions play an important role in the determination of classical and quantum states, which reveals a fundamental gap between classical and quantum world. For finite dimensional quantum system, a particle… Read more →

Quantum logical entropy: fundamentals and general properties. (arXiv:2108.02726v1 [quant-ph]) 上午10:04 | Boaz Tamir, Ismael L. Paiva, Zohar Schwartzman-Nowik, Eliahu Cohen | quant-ph updates on arXiv.org Logical entropy gives a measure, in the sense of measure theory, of the distinctions of a given partition of a set, an idea that can be naturally generalized to classical probability distributions. Here, we analyze… Read more →
