Consistent dynamics which couples classical and quantum degrees of freedom exists, provided it is stochastic. This provides a way to study the back-reaction of quantum fields on space-time which does
Isospectral twirling and quantum chaos. (arXiv:2011.06011v1 [quant-ph])
We show that the most important measures of quantum chaos like frame potentials, scrambling and Loschmidtecho can be described by the unified framework of the isospectral twirling, namely the Haar
Estimating Heating Times in Periodically Driven Quantum Many-Body Systems via Avoided Crossing Spectroscopy. (arXiv:2011.06017v1 [cond-mat.stat-mech])
Periodic driving of a quantum (or classical) many-body system can alter the systems properties significantly and therefore has emerged as a promising way to engineer exotic quantum phases, such as
Clifford operators in SU(N)1; N not odd prime. (arXiv:2011.06035v1 [hep-th])
Farinholt gives a characterization of Clifford operators for qudits; d both odd and even. In this comment it is shown that the necessary gates for the construction of Clifford operators;
Ultra-precision single-quadrature quantum magnetometry in cavity electromagnonics. (arXiv:2011.06081v1 [quant-ph])
A scheme of an ultra-sensitive magnetometer in the cavity quantum electromagnonics where the intracavity microwave mode coupled to a magnonic mode via magnetic dipole interaction is proposed. It is shown
Infinite degeneracy of Landau levels from the Euclidean symmetry with central extension revisited. (arXiv:2011.06091v1 [quant-ph])
The planar Landau system which describes the quantum mechanical motion of a charged particle in a plane with a uniform magnetic field perpendicular to the plane, is explored within pedagogical
Numerically exact treatment of dissipation in a driven two-level system. (arXiv:2011.06106v1 [quant-ph])
Recent progress in the experimental implementations of controlled quantum systems and especially of tunable dissipation for them provides an ideal starting point for precision studies of open quantum systems and
Storage capacity and learning capability of quantum neural networks. (arXiv:2011.06113v1 [quant-ph])
We study the storage capacity of quantum neural networks (QNNs) described as completely positive trace preserving (CPTP) maps, which act on an $N$-dimensional Hilbert space. We demonstrate that QNNs can
An Argument for Strong Positivity of the Decoherence Functional. (arXiv:2011.06120v1 [quant-ph])
We give an argument for strong positivity of the decoherence functional as the correct, physical positivity condition in formulations of quantum theory based fundamentally on the path integral. We extend
The Operational Choi-Jamiolkowski Isomorphism. (arXiv:2011.06126v1 [quant-ph])
In this article, I use an operational formulation of the Choi-Jamio\l{}kowski isomorphism to explore an approach to quantum mechanics in which the state is not the fundamental object. I first
