The detection and certification of entanglement and quantum correlations in materials is of
fundamental and far‐reaching importance, and has seen significant recent progress. It …

The development of quantum technologies at room temperature is an actual challenge to
overcome. The quantum properties of advanced materials must be optimized to preserve …

Entanglement is a concept that has defied common sense since the discovery of quantum
mechanics. Two particles are said to be entangled when the quantum state of each particle …

Bipartite quantum and thermal entanglement is quantified within pure and mixed states of a
mixed spin-(1/2, 1) Heisenberg dimer with the help of negativity. It is shown that the …

Entanglement is a central concept in quantum information and a key resource for many
quantum protocols. In this work we propose and analyze a class of entanglement witnesses …

Being extremely important resources in quantum information and computation, it is vital to
efficiently detect and properly characterize entangled states. We analyze in this work the …

Quantum thermodynamics is a powerful theoretical tool for assessing the suitability of
quantum materials as platforms for novel technologies. In particular, the modeling of …

The quantum entanglement measure is determined, for the first time, for a collection of spin-
1/2 arranged in a infinite chain with finite temperature and applied to a single-crystal β β-T …

Abstract We consider the spin-1/2 Ising chain model in a transverse field (TF) with added
transverse Dzyaloshinskii–Moriya (TDM) interaction in the thermodynamic limit and compute …

Free entanglement—the milestone of any quantum information processing scheme—among
the π-electronic spin and its spatial states in graphene, as a function of temperature, is the …
