(Information) Paradox Lost

Tim Maudlin Since Stephen Hawking's original 1975 paper on black hole evaporation, there has been a consensus that the problem of "loss of information" is both deep and troubling. It is also thought that resolution of the problem may hold some conceptual keys to the unification of gravity with the other forces. I argue that this consensus view is mistaken.... 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 →

Entropy evolution of moving mirrors and the information loss problem. (arXiv:1704.08613v1 [hep-th])  gr-qc updates on arXiv.org on 2017-4-29 8:01am GMT Authors: Pisin Chen, Dong-han Yeom We investigate the entanglement entropy and the information flow of two-dimensional moving mirrors. Here we point out that various mirror trajectories can help to mimic different candidate resolutions to the information loss paradox following the semi-classical quantum... Read more →

At what time does a quantum experiment have a result?   The Extended Bloch Representation of Quantum Mechanics for Infinite-Dimensional Entities. (arXiv:1704.06249v1 [quant-ph])  quant-ph updates on arXiv.org on 2017-4-21 7:39am GMT Authors: Diederik Aerts, Massimiliano Sassoli de Bianchi We show that the extended Bloch representation of quantum mechanics also applies to infinite-dimensional entities, to the extent that the number of (possibly infinitely...

Quantum detection of wormholes. (arXiv:1702.01720v2 [quant-ph] UPDATED)  gr-qc updates on arXiv.org on 2017-4-08 12:56am GMT Authors: Carlos Sabín We show how to use quantum metrology to detect a wormhole. A coherent state of the electromagnetic field experiences a phase shift with a slight dependence on the throat radius of a possible distant wormhole. We show that this tiny correction is, in...

Quantum mechanics from an epistemic state space

Per Östborn (Lund University, Sweden) We derive the Hilbert space formalism of quantum mechanics from epistemic principles. A key assumption is that a physical theory that relies on entities or distinctions that are unknowable in principle gives rise to wrong predictions. An epistemic formalism is developed, where concepts like individual and collective knowledge are used, and knowledge may be actual... Read more →
