Lossy Micromaser Battery: Almost Pure States in the Jaynes-Cummings Regime
Vahid Shaghaghi, Varinder Singh, Matteo Carrega +2
We consider a micromaser model of a quantum battery, where the battery is a single mode of the electromagnetic field in a cavity, charged via repeated interactions with a stream of…
Anomalous periodicity and parafermion hybridization in superconducting qubits
Alessio Calzona, Matteo Carrega, Luca Chirolli
Topological quantum computation relies on a protected degenerate subspace enabling complicated operations in a noise-resilient way. To this end, hybrid platforms based on non-Abeli…
Multi-mode architectures for noise-resilient superconducting qubits
Alessio Calzona, Matteo Carrega
Great interest revolves around the development of new strategies to efficiently store and manipulate quantum information in a robust and decoherence-free fashion. Several proposals…
Josephson Diode Effect in High Mobility InSb Nanoflags
Bianca Turini, Sedighe Salimian, Matteo Carrega +6
We report evidence of non-reciprocal dissipation-less transport in single ballistic InSb nanoflag Josephson junctions, owing to a strong spin-orbit coupling. Applying an in-plane m…
Dynamical heat engines with non--Markovian reservoirs
Fabio Cavaliere, Matteo Carrega, Giulio De Filippis +3
We discuss whether, and under which conditions, it is possible to realize a heat engine simply by dynamically modulating the couplings between the quantum working medium and therma…
Assessing bound states in a one-dimensional topological superconductor: Majorana versus Tamm
Lucia Vigliotti, Fabio Cavaliere, Matteo Carrega +1
Majorana bound states in topological superconductors have attracted intense research activity in view of applications in topological quantum computation. However, they are not the…
