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
