We are delighted to announce that IJQF will organize an online International Workshop on Quantum Foundations from 7 July 2018 to 21 July 2018 here. The workshop will bring together leading experts in the field, and address the most pressing problems in the foundations of quantum mechanics today. Based on the successful previous Quantum Foundations Workshop 2015, this workshop will be more… Read more →
Dimensional reduction via a novel Higgs mechanism. (arXiv:1806.07520v1 [gr-qc] CROSS LISTED) hep-th updates on arXiv.org on 2018-6-23 1:03am GMT Authors: Saurya Das, Mir Faizal Many theories of quantum gravity live in higher dimensions, and their reduction to four dimensions via mechanisms such as Kaluza-Klein compactification or brane world models have associated problems. We propose a novel mechanism of dimensional reduction via spontaneous… Read more →
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 →
