Extending the Agent in QBism. (arXiv:2004.14847v1 [quant-ph]) 下午3:48 | Jacques Pienaar | quant-ph updates on arXiv.org According to the subjective Bayesian interpretation of quantum mechanics (QBism), the instruments used to measure quantum systems are to be regarded as an extension of the senses of the agent who is using them, and quantum states describe the agent’s expectations for what they… Read more →
Subjectifying Objectivity: Delineating Tastes in Theoretical Quantum Gravity Research. (arXiv:2004.07450v1 [physics.hist-ph]) 上午8:42 | physics.hist-ph updates on arXiv.org Authors: Thomas K. Gilbert, Andrew J. Loveridge Research in Theoretical Quantum Gravity has continued expansively even as it has become detached from classic arbiters of research such as direct empirical falsification. This makes it an interesting test case for social-scientific theories of what motivates and… Read more →
Quantum Incompatibility of a Physical Context. (arXiv:2004.01008v1 [quant-ph]) 上午8:37 | E. Martins, M. F. Savi, R. M. Angelo | quant-ph updates on arXiv.org Pivotal within quantum physics, the concept of quantum incompatibility is generally related to algebraic aspects of the formalism, such as commutation relations and unbiasedness of bases. Recently, the concept was identified as a resource in tasks involving… Read more →

Searching for Coherent States, From Origins to Quantum Gravity. (arXiv:2003.11810v1 [quant-ph]) 上午8:40 | physics.hist-ph updates on arXiv.org Authors: Pierre Martin-Dussaud We discuss the notion of coherent states from three different perspectives: the seminal approach of Schroedinger, the experimental take of quantum optics, and the theoretical developments in quantum gravity. This comparative study tries to emphasise the connections between the approaches, and… Read more →
In response to reviewer comments, I am posting a sightly revised version of my previously submitted paper. Editor: please note that my emails to you are not getting through at the moment, so please consider this my resubmission. Many thanks. ABSTRACT: This paper presents an analysis of decoherence resulting from the physically real non-unitarity, or ‘objective reduction,’ that occurs in… Read more →

Newton’s discrete dynamics. (arXiv:2003.02702v1 [physics.class-ph]) 上午9:49 | physics.hist-ph updates on arXiv.org Authors: Søren Toxvaerd In 1687 Isaac Newton published PHILOSOPHI\AE \ NATURALIS PRINCIPIA MATHEMATICA, where the classical analytic dynamics was formulated. But Newton also formulated a discrete dynamics, which is the central difference algorithm, known as the Verlet algorithm. In fact Newton used the central difference to derive his second law….

Vacuum entanglement harvesting with a zero mode. (arXiv:2002.11790v1 [quant-ph]) 下午12:05 | Erickson Tjoa, Eduardo Martín-Martínez | quant-ph updates on arXiv.org We investigate vacuum entanglement harvesting in the presence of a zero mode. We show that, for a variety of detector models and couplings (namely, Unruh-DeWitt qubit and harmonic oscillator detectors, amplitude and derivative coupling), the results are strongly dependent on… Read more →
