Quantum gravity tomography. (arXiv:1806.05643v1 [hep-th])  hep-th updates on arXiv.org on 2018-6-16 1:14am GMT Authors: William Donnelly The holographic principle posits that all quantum information in a region of spacetime is encoded on its boundary. While there is strong evidence for this principle in certain models of quantum gravity in asymptotically anti-de Sitter spacetime, it is yet to be established whether holography… Read more →

Why initial system-environment correlations do not imply the failure of complete positivity: a causal perspective. (arXiv:1806.02381v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-6-09 12:56am GMT Authors: David Schmid, Katja Reid, Robert W. Spekkens The common wisdom in the field of quantum information theory is that when a system is initially correlated with its environment, the map describing its evolution may fail to be… Read more →

Continuity of measurement outcomes. (arXiv:1805.12404v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-6-02 3:59am GMT Authors: J. Sperling It is demonstrated that the collapse of the wave function is equivalent to the continuity of measurement outcomes. The latter states that a second measurement has to result in the same outcome as the first measurement of the same observable for a vanishing time… Read more →

Decoherence and Determinism in a One-Dimensional Cloud-Chamber Model  Latest Results for Foundations of Physics on 2018-4-01 12:00am GMT Abstract The hypothesis (Sparenberg et al. in EPJ Web Conf 58:01016, [1]. http://dx.doi.org/10.1051/epjconf/20135801016) that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determined by the (random) positions of atoms or molecules inside the… Read more →

Gravitation in terms of observables. (arXiv:1802.02661v1 [gr-qc])  hep-th updates on arXiv.org on 2018-2-10 12:53am GMT Authors: Rodolfo Gambini, Jorge Pullin In the 1960’s, Mandelstam proposed a new approach to gauge theories and gravity based on loops. The program for gauge theories was completed for Yang–Mills theories by Gambini and Trias in the 1980’s. Gauge theories could be understood as representations of certain… Read more →

How to Build an Infinite Lottery Machine We propose two novel alternative manners of doing so, `no-leaking’ (roughly that information gain causes disturbance) and `purity of cups’ (roughly the existence of entangled states). Interestingly, these turn out to be equivalent in any process theory with cups and caps. Additionally, we show how the standard purification postulate can then be seen… Read more →
