We propose a spin-star network, where a central spin-(1/2), acting as a quantum fuel, is
coupled to N outer spin-(1/2) particles. If the network is in thermal equilibrium with a heat …

The uncertainty principle is known as a foundational element of quantum theory, providing a
striking lower bound to quantify our prediction for the measured result of two incompatible …

The generation and preservation of entanglement is a central goal in quantum technology.
Traditionally, dissipation in quantum systems is thought to be detrimental to entanglement …

Few studies explored the dynamics of nonclassical correlations besides entanglement in
open multipartite quantum systems. Here, we address the time evolution of quantum discord …

In this paper, we study the thermal evolution of three types of quantum correlations under the
homogeneous and inhomogeneous spin star Hamiltonian. It is shown that quantum discord …

We consider spin‐chain‐star systems characterized by N‐wise many‐body interactions
between the spins in each chain and the central one. We show that such systems can be …

The uncertainty principle bounds the measurement precision of two complementary
variables and the bipartite scenario of quantum-memory-assisted entropic uncertainty …

Central spin models, where a single spinful particle interacts with a spin environment, find
wide application in quantum information technology and can be used to describe, eg, the …

Quantum effects in hybrid atomic optomechanics in a system comprising a cloud of atoms
and a mobile mirror mediated by a single‐mode cavity are studied. Tripartite nonlocality is …

The paper reports a computational study of the quantum entanglement in V12 cluster
molecular magnet. The low-temperature properties of the system are modelled with …
