Engineering of Quantum State by Time-Dependent Decoherence-Free Subspaces

open access: yes, 2015
We apply the time-dependent decoherence-free subspace theory to a Markovian open quantum system in order to present a novel proposal for quantum-state engineering program.

Controllable non-Markovianity in phase relaxation

open access: yesNew Journal of Physics, 2020
Recently remarkable progress in quantum technology has been witnessed. In view of this it is important to investigate an open quantum system as a model of such quantum devices.

Reduced quantum dynamics with initial system-environment correlations characterized by pure Markov states

open access: yes, 2016
Any tripartite state which saturates the strong subadditivity relation for the quantum entropy is defined as the Markov state.A tripartite pure state describing an open system, its environment and their purifying system isa pure Markov state iff the ...

Non-Markovian features in semiconductor quantum optics: quantifying the role of phonons in experiment and theory

open access: yesNanophotonics, 2019
We discuss phonon-induced non-Markovian and Markovian features in QD-based quantum nanooptics. We cover lineshapes in linear absorption experiments, phonon-induced incoherence in the Heitler regime, and memory correlations in two-photon coherences.

Quantum algorithm for simulating the dynamics of an open quantum system

open access: yes, 2011
In the study of open quantum systems, one typically obtains the decoherence dynamics by solving a master equation. The master equation is derived using knowledge of some basic properties of the system, the environment and their interaction: one basically

Speed limit for open quantum systems

open access: yesNew Journal of Physics, 2019
We study the quantum speed limit for open quantum systems described by the Lindblad master equation. The obtained inequality shows a trade-off relation between the operation time and the physical quantities such as the energy fluctuation and the entropy ...
