Efficiency of Dynamical Decoupling for (Almost) Any Spin-Boson Model

A Hahn, D Burgarth, D Lonigro - arxiv preprint arxiv:2409.15743, 2024 - arxiv.org
Dynamical decoupling is a technique aimed at suppressing the interaction between a
quantum system and its environment by applying frequent unitary operations on the system …

Kinetic state and emergence of Markovian dynamics in exactly solvable models of open quantum systems

AS Trushechkin - Proceedings of the Steklov Institute of Mathematics, 2024 - Springer
Typically, the theory of open quantum systems studies the dynamics of the reduced state
(density operator) of the system. However, in the early stages of evolution, it is impossible to …
