K Head-Marsden, J Flick, CJ Ciccarino… - Chemical …, 2020 - ACS Publications
Discoveries in quantum materials, which are characterized by the strongly quantum-
mechanical nature of electrons and atoms, have revealed exotic properties that arise from …

Efficient exploration of Hamiltonian parameter space for optimal control of non-Markovian open quantum systems

GE Fux, EP Butler, PR Eastham, BW Lovett… - Physical Review Letters, 2021 - APS
We present a general method to efficiently design optimal control sequences for non-
Markovian open quantum systems, and illustrate it by optimizing the shape of a laser pulse …

Capturing non-Markovian dynamics on near-term quantum computers

K Head-Marsden, S Krastanov, DA Mazziotti… - Physical Review …, 2021 - APS
With the rapid progress in quantum hardware, there has been an increased interest in new
quantum algorithms to describe complex many-body systems searching for the still-elusive …

Thermal recall: Memory-assisted Markovian thermal processes

J Czartowski, A de Oliveira Junior, K Korzekwa - PRX Quantum, 2023 - APS
We develop a resource-theoretic framework that allows one to bridge the gap between two
approaches to quantum thermodynamics based on Markovian thermal processes (which …

Non-Markov enhancement of maximum power for quantum thermal machines

P Abiuso, V Giovannetti - Physical Review A, 2019 - APS
In this work we study how the non-Markovian character of the dynamics can affect the
thermodynamic performance of a quantum thermal engine, by analyzing the maximum …

Quantum metrology in a non-Markovian quantum evolution

N Mirkin, M Larocca, D Wisniacki - Physical Review A, 2020 - APS
The problem of quantum metrology in the context of a particular non-Markovian quantum
evolution is explored. We study the dynamics of the quantum Fisher information (QFI) of a …

Information backflow as a resource for entanglement

N Mirkin, P Poggi, D Wisniacki - Physical Review A, 2019 - APS
The issue of whether non-Markovianity (NM) could be considered as a resource in quantum
information has been a subject of intense debate in recent years. Recently, a simple …

Optimal control and selectivity of qubits in contact with a structured environment

Q Ansel, J Fischer, D Sugny, B Bellomo - Physical Review A, 2022 - APS
We present a theoretical study of the optimal control of a qubit interacting with a structured
environment. We consider a model system in which the bath is a bosonic reservoir at zero …

Witnessing non-Markovian effects of quantum processes through Hilbert-Schmidt speed

HR Jahromi, K Mahdavipour, M Khazaei Shadfar… - Physical Review A, 2020 - APS
Non-Markovian effects can speed up the dynamics of quantum systems while the limits of
the evolution time can be derived by quantifiers of quantum statistical speed. We introduce a …

Convex resource theory of non-Markovianity

S Bhattacharya, B Bhattacharya… - Journal of Physics A …, 2020 - iopscience.iop.org
We establish a convex resource theory of non-Markovianity inducing information backflow
under the constraint of small time intervals within the temporal evolution. We identify the free …
