Singular-Value Statistics of Non-Hermitian Random Matrices and Open Quantum Systems [PDF]
PRX Quantum, 2023 The spectral statistics of non-Hermitian random matrices are of importance as a diagnostic tool for chaotic behavior in open quantum systems. Here, we investigate the statistical properties of singular values in non-Hermitian random matrices as an ...

Analog Quantum Simulation of the Dynamics of Open Quantum Systems with Quantum Dots and Microelectronic Circuits [PDF]
PRX Quantum, 2022 We introduce a general setup for the analog quantum simulation of the dynamics of open quantum systems based on semiconductor quantum dots electrically connected to a chain of quantum RLC electronic circuits.

Simulating Markovian Open Quantum Systems Using Higher-Order Series Expansion
International Colloquium on Automata, Languages and Programming, 2022We present an efficient quantum algorithm for simulating the dynamics of Markovian open quantum systems. The performance of our algorithm is similar to the previous state-of-the-art quantum algorithm, i.e., it scales linearly in evolution time and poly ...

Mpemba Effects in Open Nonequilibrium Quantum Systems [PDF]
Physical Review LettersWe generalize the classical thermal Mpemba effect (where an initially hot system relaxes faster to the final equilibrium state than a cold one) to open quantum systems coupled to several reservoirs.

Edge Modes and Symmetry-Protected Topological States in Open Quantum Systems
PRX Quantum, 2023Topological order offers possibilities for processing quantum information that can be immune to imperfections. However, the question of its stability out of equilibrium is relevant for experiments, where coupling to an environment is unavoidable. In this

Quantum projection filtering for open quantum systems
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017This paper presents an approximation quantum projection filtering strategy, aiming to reduce the computational cost in calculating the standard quantum filter equation in time. By using a differential geometric approach, the trajectory of the resulting quantum projection filter is constrained to evolve in a finite-dimensional differentiable manifold ...

Mixing Time of Open Quantum Systems via Hypocoercivity.
Physical Review LettersUnderstanding the mixing of open quantum systems is a fundamental problem in physics and quantum information science. Existing approaches for estimating the mixing time often rely on the spectral gap estimation of the Lindbladian generator, which can be ...

Quantum systems exhibiting chaotic dynamics in their classical limit provide a stimulating testing ground for an information theoretical interpretation of dynamical properties: In isolated quantum systems, the positive information production characteristic of classical chaotic systems is replaced by quasiperiodic behavior.
