Non-Markovian dynamics control of spin-1/2 system interacting with magnets

open access: yesNew Journal of Physics, 2021
The unavoidable interaction of an open quantum system with its surrounding environment may follow non-Markovian dynamics behavior, which causes its memory effects to play a key role in many quantum technologies.

Characterisation of the Degree of Musical Non-Markovianity

open access: yesJournal of Creative Music Systems, 2022
As an aid for musical analysis, in computational musicology mathematical and informatics tools have been developed to characterise quantitatively some aspects of musical compositions.

On Non-Markovian Performance Models

open access: yesCoRR, 2020
We present an approach that can be useful when the network or system performance is described by a model that is not Markovian. Although most performance models are based on Markov chains or Markov processes, in some cases the Markov property does not hold. This can occur, for example, when the system exhibits long range dependencies.

Entanglement, non-Markovianity, and causal non-separability

open access: yesNew Journal of Physics, 2018
Quantum mechanics, in principle, allows for processes with indefinite causal order. However, most of these causal anomalies have not yet been detected experimentally.

Engineering non-Markovianity from defect-phonon interactions

open access: yesNew Journal of Physics, 2023
Understanding defect-phonon interactions in solid-state devices is crucial for improving our current knowledge of quantum platforms. In this work, we develop first-principles calculations for a defect composed of two spin- $1/2$ particles that interact ...

Non-Markovianity in the collision model with environmental block

open access: yesNew Journal of Physics, 2018
We present an extended collision model to simulate the dynamics of an open quantum system. In our model, the unit to represent the environment is, instead of a single particle, a block which consists of a number of environment particles.

Quantum Metrology in Non-Markovian Environments [PDF]

open access: yesPhysical Review Letters, 2012
We analyze precision bounds for a local phase estimation in the presence of general, non-Markovian phase noise. We demonstrate that the metrological equivalence of product and maximally entangled states that holds under strictly Markovian dephasing fails in the non-Markovian case.

Mixing-induced quantum non-Markovianity and information flow

open access: yesNew Journal of Physics, 2018
Mixing dynamical maps describing open quantum systems can lead from Markovian to non-Markovian processes. Being surprising and counter-intuitive, this result has been used as argument against characterization of non-Markovianity in terms of information ...

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.
