Geodesic-based optimal control for leakage suppression in superconducting qubits
Adonai Hilário da Silva, Tanmoy Pandit, Francesco Cosco
Superconducting qubits are often based on the first two energy levels of a physical anharmonic LC oscillator. Since the anharmonicity of such systems is usually much lower than the…
Enhancing qubit readout with Bayesian Learning
F. Cosco, N. Lo Gullo
We introduce an efficient and accurate readout measurement scheme for single and multi-qubit states. Our method uses Bayesian inference to build an assignment probability distribut…
Theory of superdiffusive spin transport in noncollinear magnetic multilayers
Pavel Baláž, Maciej Zwierzycki, Francesco Cosco +3
Ultrafast demagnetization induced by femtosecond laser pulses in thin metallic layers is caused by the outflow of spin-polarized hot electron currents describable by the superdiffu…
Enhanced force sensitivity and entanglement in periodically driven optomechanics
F. Cosco, J. S. Pedernales, M. B. Plenio
Squeezing is a resource that enables precision enhancements in quantum metrology and can be used as a basis for the generation of entanglement by linear optics. While strong squeez…
Spectral properties of correlated quantum wires and carbon nanotubes within the Generalized Kadanoff-Baym Ansatz
F. Cosco, N. W. Talarico, R. Tuovinen +1
We investigate the spectral properties of an open interacting system by solving the Generalized Kadanoff-Baym Ansatz (GKBA) master equation for the single-particle density matrix,…
Decoherence-Free Rotational Degrees of Freedom for Quantum Applications
Julen S. Pedernales, Francesco Cosco, Martin B. Plenio
We employ spherical -designs for the systematic construction of solids whose rotational degrees of freedom can be made robust to decoherence due to external fluctuating fields w…
Reservoir Engineering using Quantum Optimal Control for Qubit Reset
Daniel Basilewitsch, Francesco Cosco, Nicola Lo Gullo +4
We determine how to optimally reset a superconducting qubit which interacts with a thermal environment in such a way that the coupling strength is tunable. Describing the system in…
Momentum-resolved spectroscopy of a 1D superfluid using a single atomic impurity
Francesco Cosco, Massimo Borrelli, Francesco Plastina +1
We present a general and non-invasive probing scheme to perform full momentum-resolved spectroscopy of a cold atomic gas loaded into an optical lattice using a single quantum impur…
Entanglement Protection via Periodic Environment Resetting in Continuous Time Quantum Dynamical Processes
Thomas Bullock, Francesco Cosco, Marwan Haddara +8
The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a coup…
Irreversible Work and Orthogonality Catastrophe in the Aubry-André model
Francesco Cosco
We address the statistical orthogonality catastrophe induced by a local quench in the Aubry-André model from the perspective of nonequilibrium thermodynamics. We study the average…
Memory effects in a quasi-periodic Fermi lattice
Francesco Cosco, Sabrina Maniscalco
We investigate a system of fermions trapped in a quasi-periodic potential from an open quantum system theory perspective, designing a protocol in which an impurity atom (a two leve…
Emergence of anomalous dynamics from the underlying singular continuous spectrum in interacting many-body systems
J. Settino, N. W. Talarico, F. Cosco +3
We investigate the dynamical properties of an interacting many-body system with a non-trivial energy potential landscape that may induce a singular continuous single-particle energ…
Statistics of orthogonality catastrophe events in localised disordered lattices
Francesco Cosco, Massimo Borrelli, Elsi-Mari Laine +3
We address the phenomenon of statistical orthogonality catastrophe in insulating disordered systems. More in detail, we analyse the response of a system of non-interacting fermions…
Bose-Hubbard lattice as a controllable environment for open quantum systems
Francesco Cosco, Massimo Borrelli, Juan José Mendoza-Arenas +3
We investigate the open dynamics of an atomic impurity embedded in a one-dimensional Bose-Hubbard lattice. We derive the reduced evolution equation for the impurity and show that t…
Momentum-Resolved and Correlations Spectroscopy Using Quantum Probes
Francesco Cosco, Massimo Borrelli, Francesco Plastina +1
We address some key conditions under which many-body lattice models, intended mainly as simulated condensed matter systems, can be investigated via immersed, fully controllable qua…
