Triply Positive Matrices and Quantum Measurements Motivated by QBism. (arXiv:1812.08762v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-12-22 3:56am GMT Authors: John B. DeBrota, Christopher A. Fuchs, Blake C. Stacey We study a class of quantum measurements that furnish probabilistic representations of finite-dimensional quantum theory. The Gram matrices associated with these Minimal Informationally Complete quantum measurements (MICs) exhibit a rich structure. They are “positive”… Read more →

Complete list of Bell inequalities with four binary settings. (arXiv:1811.11820v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-12-01 1:20am GMT Authors: E. Zambrini Cruzeiro, N. Gisin We give the complete list of 175 facet Bell inequalities for the case where Alice and Bob each choose their measurements from a set of four binary outcome measurements. For each inequality we compute the maximum quantum… Read more →

Does the PBR Theorem Rule out a Statistical Understanding of QM?  Latest Results for Foundations of Physics on 2018-12-01 12:00am GMT Abstract The PBR theorem gives insight into how quantum mechanics describes a physical system. This paper explores PBRs’ general result and shows that it does not disallow the ensemble interpretation of quantum mechanics and maintains, as it must, the… Read more →

A non-equilibrium system as a demon. (arXiv:1811.02453v2 [cond-mat.mes-hall] UPDATED)  quant-ph updates on arXiv.org on 2018-11-10 1:30am GMT Authors: Rafael Sánchez, Janine Splettstoesser, Robert S. Whitney Maxwell demons are creatures that are imagined to be able to reduce the entropy of a system without performing any work on it. Conventionally, such a Maxwell demon’s intricate action consists in measuring individual particles and subsequently performing… Read more →

Why The Cosmological Constant is a Boundary Condition. (arXiv:1811.00130v1 [hep-th])  hep-th updates on arXiv.org on 2018-11-04 12:52am GMT Authors: Tom Banks, Willy Fischler We review arguments that the cosmological constant (c.c.) should not be thought of as a local contribution to the energy density, but rather as an infrared boundary condition specifying particular models of quantum gravity. Certifying the Building Blocks of… Read more →

On the Consistency of the Wheeler-DeWitt Equation in the Quantized Eddington-inspired Born-Infeld Gravity. (arXiv:1810.10918v1 [gr-qc])  hep-th updates on arXiv.org on 2018-10-26 3:30am GMT Authors: Mariam Bouhmadi-López, Che-Yu Chen, Pisin Chen We re-examine the quantum geometrodynamical approach within the Eddington-inspired-Born-Infeld theory of gravity, which was first proposed in our previous work [1]. A thorough analysis of the classical Hamiltonian with constraints is carried and… Read more →
