Quantum Information Scrambling in Non-Markovian Open Quantum System [PDF]

open access: yesEntropy, 2022
In this paper, we investigate the dynamics of a spin chain whose two end spins interact with two independent non-Markovian baths by using the non-Markovian quantum state diffusion (QSD) equation approach.

Work Measurement in OPEN Quantum System [PDF]

open access: yesEntropy, 2022
Work is an important quantity in thermodynamics. In a closed quanutm system, the two-point energy measurements can be applied to measure the work but cannot be utilized in an open quantum system.

Singly-excited resonant open quantum system Tavis-Cummings model with quantum circuit mapping [PDF]

open access: yesScientific Reports, 2023
Tavis-Cummings (TC) cavity quantum electrodynamical effects, describing the interaction of N atoms with an optical resonator, are at the core of atomic, optical and solid state physics.

Scarring in open quantum systems [PDF]

open access: yesPhysical Review E, 2007
We study scarring phenomena in open quantum systems. We show numerical evidence that individual resonance eigenstates of an open quantum system present localization around unstable short periodic orbits in a similar way as their closed counterparts.

Time Series Prediction of Open Quantum System Dynamics by Transformer Neural Networks [PDF]

open access: yesEntropy
The dynamics of open quantum systems play a crucial role in quantum information science. However, obtaining numerically exact solutions for the Lindblad master equation is often computationally expensive. Recently, machine learning techniques have gained

Large-scale stochastic simulation of open quantum systems [PDF]

open access: yesNature Communications
Understanding interactions between quantum systems and their environments is crucial for developing stable quantum technologies and accurate physical models. Yet, simulating open quantum systems with non-unitary dynamics remains computationally demanding.

Quantum Zeno Effect in Open Quantum Systems [PDF]

open access: yesAnnales Henri Poincaré, 2021
AbstractWe prove the quantum Zeno effect in open quantum systems whose evolution, governed by quantum dynamical semigroups, is repeatedly and frequently interrupted by the action of a quantum operation. For the case of a quantum dynamical semigroup with a bounded generator, our analysis leads to a refinement of existing results and extends them to a ...

Hamiltonian open quantum system toolkit

open access: yesCommunications Physics, 2022
In quantum computing, simulating continuously evolving open quantum systems is key to describe dynamical processes on noisy quantum devices. Here, the authors present an open-source software package “Hamiltonian Open Quantum System Toolkit” (HOQST) for ...

Accessible coherence in open quantum system dynamics [PDF]

open access: yesQuantum, 2020
Quantum coherence generated in a physical process can only be cast as a potentially useful resource if its effects can be detected at a later time. Recently, the notion of non-coherence-generating-and-detecting (NCGD) dynamics has been introduced and ...

OPEN QUANTUM SYSTEMS [PDF]

open access: yesInternational Journal of Modern Physics E, 1994
The damping of the harmonic oscillator is studied in the framework of the Lindblad theory for open quantum systems. A generalization of the fundamental constraints on quantum mechanical diffusion coefficients which appear in the master equation for the damped quantum oscillator is presented; the Schrödinger, Heisenberg and Weyl-Wigner-Moyal ...
