Geometric Aspects of Entanglement
Lucio De Simone, Lorenzo Capra, Arthur Vesperini +3
Quantum entanglement is a fundamental resource in quantum information theory, yet its general characterization and quantification remain challenging, especially in multipartite sys…
Enhancing Quantum Entanglement Through Parametric Control of Atom-Cavity States
Arthur Vesperini, Roberto Franzosi
Dicke states form a class of entangled states that has attracted much attention for their applications in various quantum algorithms. They emerge as eigenstates of the Tavis-Cummin…
Entanglement Signature of the Superradiant Quantum Phase Transition
Arthur Vesperini, Matteo Cini, Roberto Franzosi
Entanglement and quantum correlations between atoms are not usually considered key ingredients of the superradiant phase transition. Here we consider the Tavis-Cummings model, a so…
Entanglement, quantum correlators and connectivity in graph states
Arthur Vesperini, Roberto Franzosi
In this work, we present a comprehensive exploration of the entanglement and graph connectivity properties of graph states. We quantify the entanglement in pseudo graph states usin…
Unveiling the geometric meaning of quantum entanglement: discrete and continuous variable systems
Arthur Vesperini, Ghofrane Bel-Hadj-Aissa, Lorenzo Capra +1
We show that the manifold of quantum states is endowed with a rich and nontrivial geometric structure. We derive the Fubini-Study metric of the projective Hilbert space of a multi-…
Correlations and projective measurements in maximally entangled multipartite states
Arthur Vesperini
Multipartite quantum states constitute the key resource for quantum computation. The understanding of their internal structure is thus of great importance in the field of quantum i…
Entanglement and Quantum Correlation Measures from a Minimum Distance Principle
Arthur Vesperini, Ghofrane Bel-Hadj-Aissa, Roberto Franzosi
Entanglement, and quantum correlation, are precious resources for quantum technologies implementation based on quantum information science, such as, for instance, quantum communica…
Fast collective oscillations and clustering phenomena in an antiferromagnetic mean-field model
Arthur Vesperini, Roberto Franzosi, Stefano Ruffo +2
We study the out-of-equilibrium properties of the antiferromagnetic Hamiltonian Mean-Field model at low energy. In this regime, the Hamiltonian dynamics exhibits the presence of a…
