Weak Gravitational Field Effects on Optical Bell Tests. (arXiv:1908.08179v1 [quant-ph]) 下午12:23 | quant-ph updates on arXiv.org Authors: M. Rivera-Tapia, A. Delgado, G. F. Rubilar The technological refinement of experimental techniques has recently allowed the generation of two-photon polarization entangled states at low Earth orbit, which have been subsequently applied to quantum communications. This achievement paves the way to study the interplay between General… Read more →

From probabilistic mechanics to quantum theory. (arXiv:1907.08513v1 [quant-ph]) 下午3:18 | quant-ph updates on arXiv.org Authors: Ulf Klein We show that quantum theory (QT) is a substructure of classical probabilistic physics. The central quantity of the classical theory is Hamilton’s function $H(q,p)$, which determines canonical equations, a corresponding flow $\phi_{t}^{H}$, and a Liouville equation for the probability density $\rho(q,p,t)$. We extend this… Read more →

A minisuperspace model of compact phase space gravity. (arXiv:1904.11338v1 [gr-qc])  hep-th updates on arXiv.org on 2019-4-27 12:44am GMT Authors: Danilo Artigas Guimarey, Jakub Mielczarek, Carlo Rovelli The kinematical phase space of classical gravitational field is flat (affine) and unbounded. Because of this, field variables may tend to infinity leading to appearance of singularities, which plague Einstein’s theory of gravity. The purpose of this… Read more →

Dimensional reduction via a novel Higgs mechanism. (arXiv:1806.07520v1 [gr-qc] CROSS LISTED)  hep-th updates on arXiv.org on 2018-6-23 1:03am GMT Authors: Saurya Das, Mir Faizal Many theories of quantum gravity live in higher dimensions, and their reduction to four dimensions via mechanisms such as Kaluza-Klein compactification or brane world models have associated problems. We propose a novel mechanism of dimensional reduction via spontaneous… Read more →

Would quantum entanglement be increased by anti-Unruh effect?. (arXiv:1802.07886v1 [gr-qc])  hep-th updates on arXiv.org on 2018-2-24 1:22pm GMT Authors: Taotao Li, Baocheng Zhang, Li You We study the “anti-Unruh effect” for an entangled quantum state in reference to the counterintuitive cooling previously pointed out for an accelerated detector coupled to the vacuum. We show that quantum entanglement for an initially entangled (spacelike separated)… Read more →

Quantum Probabilities as Behavioral Probabilities. (arXiv:1703.05691v1 [q-bio.NC])  quant-ph updates on arXiv.org on 2017-3-18 9:36am GMT Authors: V.I. Yukalov, D. Sornette We demonstrate that behavioral probabilities of human decision makers share many common features with quantum probabilities. This does not imply that humans are some quantum objects, but just shows that the mathematics of quantum theory is applicable to the description of human… Read more →
