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…
Entanglement Dynamics in Katz-Weighted Graph States
Lucio De Simone, Lorenzo Capra, Roberto Franzosi
We investigate the entanglement dynamics of quantum states defined on graphs with non-local Ising interactions governed by the Katz kernel of the underlying network. The interactio…
A Geometric Theory of Quantum Entanglement
Lorenzo Capra, Lucio de Simone, Roberto Franzosi
Entanglement Distance (ED) was originally proposed as a geometric measure of entanglement derived from the Fubini-Study metric on the projective Hilbert space. Independently, the M…
Entanglement in Quantum Systems Based on Directed Graphs
Lucio De Simone, Roberto Franzosi
We investigate the entanglement properties of quantum states associated with directed graphs. Using a measure derived from the Fubini-Study metric, we quantitatively relate multipa…
Entanglement in Directed Graph States
Lucio De Simone, Roberto Franzosi
We investigate a family of quantum states defined by directed graphs, where the oriented edges represent interactions between ordered qubits. As a measure of entanglement, we adopt…
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…
