Title: Quantum Lyapunov exponents and complex spacing ratios: two measures of Dissipative Quantum Chaos
Authors: Igor Yusipov, Mikhail Ivanchenko
Abstract summary: We propose two approaches to classifying open quantum systems. One is based on spectral properties of generators of open quantum evolution, the other on Lyapunov exponents. By using two quantum models, we try to understand whether there is an agreement between the corresponding categorizations.

Abstract: The agenda of Dissipative Quantum Chaos is to create a toolbox which would allow us to categorize open quantum systems into "chaotic" and "regular" ones. Two approaches to this categorization have been proposed recently. One of them is based on spectral properties of generators of open quantum evolution. The other one utilizes the concept of Lyapunov exponents to analyze quantum trajectories obtained by unraveling this evolution. By using two quantum models, we relate the two approaches and try to understand whether there is an agreement between the corresponding categorizations. Our answer is affirmative.

We show that an arbitrary contextuality game can be compiled into an operational "test of contextuality" involving a single quantum device. Our work can be seen as using cryptography to enforce spatial separation within subsystems of a single quantum device.

Coupled vertical double quantum dots at single-hole occupancy [37.69303106863453]
We control vertical double quantum dots confined in a double quantum well, silicon-germanium heterostructure. We sense individual charge transitions with a single-hole transistor. tuning the vertical double quantum dot to the (1,1) charge state confines a single hole in each quantum well beneath a single plunger gate.

Entanglement measures for two-particle quantum histories [0.0]
We prove that bipartite quantum histories are entangled if and only if the Schmidt rank of this matrix is larger than 1. We then illustrate the non-classical nature of entangled histories with the use of Hardy's overlapping interferometers.

Quantum representation of finite groups [0.0]
The concept of quantum representation of finite groups (QRFG) has been a fundamental aspect of quantum computing for quite some time. We provide a formal definition of this concept using both group theory and differential geometry. Our work proves the existence of a quantum representation for any finite group and outlines two methods for translating each generator of the group into a quantum circuit.

Quantum indistinguishability through exchangeable desirable gambles [69.62715388742298]
Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.
