Quantum Probes for Ohmic Environments at Thermal Equilibrium
Fahimeh Salari Sehdaran, Matteo Bina, Claudia Benedetti +1
It is often the case that the environment of a quantum system may be described as a bath of oscillators with Ohmic density of states. In turn, the precise characterization of these…
Entanglement generation in the ultra-strongly coupled Rabi model
Matteo Bina, Stefano Maffezzoli Felis, Stefano Olivares
We analyze the dynamics of the quantum Rabi model for two qubits interacting through a common bosonic field mode (resonator), focusing on the generation and detection of maximally…
Monitoring atom-atom entanglement and decoherence in a solvable tripartite open system in cavity QED
Matteo Bina, Federico Casagrande, Alfredo Lulli +1
We present a fully analytical solution of the dynamics of two strongly-driven atoms resonantly coupled to a dissipative cavity field mode. We show that an initial atom-atom entangl…
Drawbacks of the use of fidelity to assess quantum resources
Matteo Bina, Antonio Mandarino, Stefano Olivares +1
Fidelity is a figure of merit widely employed in quantum technology in order to quantify similarity between quantum states and, in turn, to assess quantum resources or reconstructi…
Squeezing of mechanical motion via qubit-assisted control
Marco G. Genoni, Matteo Bina, Stefano Olivares +2
We propose a feedback control mechanism for the squeezing of the phononic mode of a mechanical oscillator. We show how, under appropriate working conditions, a simple adiabatic app…
Collapse and revival of quantum coherence for a harmonic oscillator interacting with a classical fluctuating environment
Jacopo Trapani, Matteo Bina, Sabrina Maniscalco +1
We address the dynamics of nonclassicality for a quantum system interacting with a noisy fluctuating environment described by a classical stochastic field. As a paradigmatic exampl…
