Quantum discord and Fisher information for two-qubit system in the presence of thermal fields

open access: yesAIP Advances, 2023
We consider a double Jaynes–Cummings model for a system of two atoms that interact with a radiation field defined in a thermal spin state. We examine the impact of the parameters of the quantum model on the temporal evolution of quantum discord, quantum ...

The Interoperability Challenge in DFT Workflows Across Implementations

open access: yesAdvanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

How discord underlies the noise resilience of quantum illumination

open access: yesNew Journal of Physics, 2016
The benefits of entanglement can outlast entanglement itself. In quantum illumination, entanglement is employed to better detect reflecting objects in environments so noisy that all entanglement is destroyed.

Branching States as The Emergent Structure of a Quantum Universe [PDF]

open access: yesQuantum
Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insights about the emergence of classical phenomenology, centered around quantum

Large Language Model‐Based Chatbots in Higher Education

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation

Quantum resource theories in quantum atmosphere

open access: yesPhysics Letters B
Recent progress suggests that Hawking radiation originates not from the black hole’s event horizon but from a quantum atmosphere outside the horizon. Consider this, the current work focuses on revealing the effect of the quantum atmosphere on various ...

Quantum coherence and geometric quantum discord [PDF]

open access: yesPhysics Reports, 2018
Quantum coherence and quantum correlations are of fundamental and practical significance for the development of quantum mechanics.They are also cornerstones of quantum computation and quantum communication theory. Searching physically meaningful and mathematically rigorous quantifiers of them are long-standing concerns of the community of quantum ...

Global quantum correlations in finite-size spin chains

open access: yesNew Journal of Physics, 2013
We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently proposed measure for global quantum correlations (Rulli and Sarandy 2011 Phys.
