Experimental progress on quantum coherence: detection, quantification, and manipulation

KD Wu, A Streltsov, B Regula, GY Xiang… - Advanced Quantum …, 2021 - Wiley Online Library
Quantum coherence is a fundamental property of quantum systems, separating quantum
from classical physics. Recently, there has been significant interest in the characterization of …

Steady-state charging of quantum batteries via dissipative ancillas

FH Kamin, S Salimi, MB Arjmandi - Physical Review A, 2024 - APS
We investigate the steady-state charging process of a single-cell quantum battery
embedded in an N-cell star network of qubits, each interacting with a fermion reservoir …

Ergotropy from coherences in an open quantum system

B Çakmak - Physical Review E, 2020 - APS
We show that it is possible to have nonzero ergotropy in the steady states of an open
quantum system consisting of qubits that are collectively coupled to a thermal bath at a finite …

Study of coherence and mixedness in meson and neutrino systems

K Dixit, J Naikoo, S Banerjee, AK Alok - The European Physical Journal C, 2019 - Springer
We study the interplay between coherence and mixedness in meson and neutrino systems.
The dynamics of the meson system is treated using the generic decoherence model taking …

Quantum synchronization of few-body systems under collective dissipation

G Karpat, I Yalçınkaya, B Çakmak - Physical Review A, 2020 - APS
We explore the environment-induced synchronization phenomenon in two-level systems in
contact with a thermal dissipative environment. We first discuss the conditions under which …

Detecting non-Markovianity via quantified coherence: theory and experiments

KD Wu, Z Hou, GY Xiang, CF Li, GC Guo… - npj Quantum …, 2020 - nature.com
The dynamics of open quantum systems and manipulation of quantum resources are both of
fundamental interest in quantum physics. Here, we investigate the relation between …

Quantum correlations and speed limit of central spin systems

D Tiwari, KG Paulson, S Banerjee - Annalen der Physik, 2023 - Wiley Online Library
In this article, single, and two‐qubit central spin systems interacting with spin baths are
considered and their dynamical properties are discussed. The cases of interacting and non …

Facets of quantum information under non-Markovian evolution

J Naikoo, S Dutta, S Banerjee - Physical Review A, 2019 - APS
We consider two non-Markovian models: random telegraph noise and non-Markovian
dephasing. The memory in these models is studied from the perspective of quantum Fisher …

Predicting the onset of quantum synchronization using machine learning

F Mahlow, B Çakmak, G Karpat, İ Yalçınkaya… - Physical Review A, 2024 - APS
We have applied a machine learning algorithm to predict the emergence of environment-
induced spontaneous synchronization between two qubits in an open system setting. In …

Exploring the non-Markovian dynamics in depolarizing maps

A Abu-Nada, S Banerjee, VB Sabale - Physical Review A, 2024 - APS
The non-Markovian depolarizing channel is explored from the perspective of understanding
its non-Markovian behavior as well as the occurrence of singularities. The study brings …
