Weekly Papers on Quantum Foundations (19)

Page-Wootters formulation of indefinite causal order. (arXiv:2105.02304v1 [quant-ph]) 上午9:33 | Veronika Baumann, Marius Krumm, Philippe Allard Guérin, Časlav Brukner | quant-ph updates on arXiv.org One of the most fundamental open problems in physics is the unification of general relativity and quantum theory to a theory of quantum gravity. An aspect that might become relevant in such a theory is that… Read more →

A local hidden-variable model for experimental tests of the GHZ puzzle. (arXiv:2104.14503v1 [quant-ph]) 上午10:02 | Brian R. La Cour | quant-ph updates on arXiv.org The Greenberger-Horne-Zeilinger (GHZ) puzzle has been used to study quantum nonlocality and provide an all-or-nothing, no-go theorem for local hidden-variable models. Recent experiments using coincident-detected entangled photons prepared in a three-particle GHZ state have been used… Read more →

Quantum Origins of the Density Operator. (arXiv:2104.07465v1 [physics.gen-ph]) 上午10:31 | Mark G. Kuzyk | quant-ph updates on arXiv.org Students in quantum mechanics class are taught that the wave function contains all knowable information about an isolated system. Later in the course, this view seems to be contradicted by the mysterious density matrix, which introduces a new set of probabilities in… Read more →
