Dissipation-assisted preparation of Floquet-Laughlin states in superconducting circuits
Luis C. Steinfadt, André Eckardt, Francesco Petiziol
Fractional Chern insulators (FCIs) are lattice analogs of fractional quantum Hall systems, where the interplay of strong interactions with a frustrated tunnelling kinetics leads to…
Multipassage Landau-Zener tunneling oscillations in transverse/longitudinal dual dressing of atomic qubits
Alessandro Fregosi, Carmela Marinelli, Carlo Gabbanini +7
We investigate the time evolution of a non-resonant dressed-atom qubit in an XZ original configuration. It is composed of two electromagnetic fields, one oscillating parallel and t…

Leonardo Ratini, Giacomo Sansone, Elena Garlatti +3
Molecular nanomagnets are quantum spin systems potentially serving as qudits for future quantum technologies thanks to their many accessible low-energy states. At low temperatures,…

Peter Græns Larsen, Anne E. B. Nielsen, André Eckardt +1
Quantum many-body scars are energy eigenstates which fail to reproduce thermal expectation values of local observables, in systems where the rest of the many-body spectrum fulfils…
