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 →

A theorem about time evolution in the quantum mechanics. (arXiv:1805.03689v1 [quant-ph])  hep-th updates on arXiv.org on 2018-5-11 3:26am GMT Authors: M. A. Rajabpour Under broad conditions, we prove that the probability amplitudes in the quantum mechanics are either always constant in time or changing continuously in any interval of time. Testing Lorentz- and CPT-invariance with ultracold neutrons. (arXiv:1805.04062v1 [hep-th])  hep-th updates… Read more →

Unwinding Short-Range Entanglement. (arXiv:1804.11236v1 [quant-ph] CROSS LISTED)  hep-th updates on arXiv.org on 2018-5-05 1:16am GMT Authors: Abhishodh Prakash, Juven Wang, Tzu-Chieh Wei Symmetry-Protected Topological (SPT) phases are short-range entangled (SRE) gapped phases of quantum matter protected by global symmetries, that cannot be unitarily and adiabatically deformed to a trivial phase without closing the gap or breaking symmetry. In this work, we show that,… Read more →

Are there really conformal frames? Uniqueness of affine inflation. (arXiv:1802.01247v2 [gr-qc] UPDATED)  hep-th updates on arXiv.org on 2018-4-28 8:09am GMT Authors: Hemza Azri Here we concisely review the nonminimal coupling dynamics of a single scalar field in the context of purely affine gravity and extend the study to multifield dynamics. The coupling is performed via an affine connection and its associated… Read more →

H-theorem and Maxwell Demon in Quantum Physics. (arXiv:1804.06886v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-21 2:11am GMT Authors: N.S. Kirsanov, A.V. Lebedev, I.A. Sadovskyy, M.V. Suslov, V.M. Vinokur, G. Blatter, G.B. Lesovik The Second Law of Thermodynamics states that temporal evolution of an isolated system occurs with non-diminishing entropy. In quantum realm, this holds for energy-isolated systems the evolution of which is described by the so-called unital… Read more →

A Finite Theory of Qubit Physics. (arXiv:1804.01734v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-07 1:45am GMT Authors: T.N.Palmer Hardy’s axiomatic approach to the quantum theory of discrete Hilbert Spaces reveals that just one principle distinguishes it from classical probability theory: there should be continuous (and hence infinitesimal) reversible transformations between any pair of pure states – the single word `continuous’ giving… 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 →
