Dissipative state transfer and Maxwell's demon in single quantum trajectories: Excitation transfer between two noninteracting qubits via unbalanced dissipation rates
Fabrizio Minganti, Vincenzo Macrì, Alessio Settineri +2
We introduce a protocol to transfer excitations between two noninteracting qubits via purely dissipative processes (i.e., in the Lindblad master equation there is no coherent inter…
Conversion of Mechanical Noise into Correlated Photon Pairs: Dynamical Casimir effect from an incoherent mechanical drive
Alessio Settineri, Vincenzo Macrì, Luigi Garziano +3
We show that the dynamical Casimir effect in an optomechanical system can be achieved under incoherent mechanical pumping. We adopt a fully quantum-mechanical approach for both the…
Emission of photon pairs by mechanical stimulation of the squeezed vacuum
Wei Qin, Vincenzo Macrì, Adam Miranowicz +2
To observe the dynamical Casimir effect (DCE) induced by a moving mirror is a long-standing challenge because the mirror velocity needs to approach the speed of light. Here, we pre…
Simple preparation of Bell and GHZ states using ultrastrong-coupling circuit QED
Vincenzo Macrì, Franco Nori, Anton Frisk Kockum
The ability to entangle quantum systems is crucial for many applications in quantum technology, including quantum communication and quantum computing. Here, we propose a new, simpl…
Dissipation and Thermal Noise in Hybrid Quantum Systems in the Ultrastrong Coupling Regime
Alessio Settineri, Vincenzo Macrì, Alessandro Ridolfo +4
The interaction among the components of a hybrid quantum system is often neglected when considering the coupling of these components to an environment. However, if the interaction…
