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…
