Spacetime and Physical Equivalence   Fundamental limits on quantum dynamics based on entropy change. (arXiv:1707.06584v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-7-21 2:13am GMT Authors: Siddhartha Das, Sumeet Khatri, George Siopsis, Mark M. Wilde It is well known in the realm of quantum mechanics and information theory that the entropy is non-decreasing for the class of unital physical processes. However, in general, the entropy...

Thermodynamics as a Consequence of Information Conservation. (arXiv:1707.01750v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-7-07 8:21am GMT Authors: Manabendra Nath Bera, Arnau Riera, Maciej Lewenstein, Andreas Winter In this work we formulate thermodynamics as an exclusive consequence of information conservation. The framework can be applied to most general situations, beyond the traditional assumptions in thermodynamics, where systems and thermal-baths could be quantum, of arbitrary... Read more →

Simple derivation of the Weyl and Dirac quantum cellular automata  PRA: Quantum information on 2017-6-30 2:00pm GMT Author(s): Philippe Raynal We consider quantum cellular automata on a body-centered cubic lattice and provide a simple derivation of the only two homogenous, local, isotropic, and unitary two-dimensional automata [G. M. D'Ariano and P. Perinotti,Phys. Rev. A 90, 062106 (2014)]. Our derivation relies on... Read more →

Fixing extensions to General Relativity in the non-linear regime. (arXiv:1706.07421v1 [gr-qc])  hep-th updates on arXiv.org on 2017-6-24 7:39am GMT Authors: Juan Cayuso, Néstor Ortiz, Luis Lehner The question of what gravitational theory could supersede General Relativity has been central in theoretical physics for decades. Many disparate alternatives have been proposed motivated by cosmology, quantum gravity and phenomenological angles, and have been subjected to... Read more →

Can we Falsify the Consciousness-Causes-Collapse Hypothesis in Quantum Mechanics?. (arXiv:1609.00614v2 [quant-ph] UPDATED)  physics.hist-ph updates on arXiv.org on 2017-6-10 3:32am GMT Authors: J. Acacio de Barros, Gary Oas In this paper we examine some proposals to disprove the hypothesis that the interaction between mind and matter causes the collapse of the wave function, showing that such proposals are fundamentally flawed. We then describe... Read more →

Aspects of Symmetry, Topology and Anomalies in Quantum Matter. (arXiv:1602.05569v1 [cond-mat.str-el] CROSS LISTED)  quant-ph updates on arXiv.org on 2017-5-26 3:49am GMT Authors: Juven C. Wang In this thesis, we explore the aspects of symmetry, topology and anomalies in quantum matter with entanglement from both condensed matter and high energy theory viewpoints. The focus of our research is on the gapped many-body... Read more →

2017 International Workshop: Collapse of the Wave Function

2017 International Workshop: Collapse of the Wave Function

Today, collapse theories, together with Bohm's theory and Everett’s theory, are widely regarded as three main realistic alternatives to standard quantum mechanics. However, there have been controversies on the origin, ontology and models of wave-function collapse. The main purpose of this online workshop is to highlight the existing debates and address the controversies. Another purpose of this workshop is to get some constructive inputs to the... Read more →

Quantum theory as a self-referential theory of inference. (arXiv:1705.04307v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-5-13 3:42am GMT Authors: John Realpe-Gómez Here we derive the formalism of quantum theory from two intuitive principles: (i) inference is a physical process performed by physical systems, observers, which are part of the experimental setup--- this implies non-commutativity; (ii) experiments must be described from a...

Test of a hypothesis of realism in quantum theory using a Bayesian approach  PRA: Fundamental concepts on 2017-5-05 2:00pm GMT Author(s): N. Nikitin and K. Toms In this paper we propose a time-independent equality and time-dependent inequality, suitable for an experimental test of the hypothesis of realism. The derivation of these relations is based on the concept of conditional probability and on Bayes'... Read more →
