Continuous-time quantum walk on spatially correlated noisy lattices
Matteo A. C. Rossi, Claudia Benedetti, Massimo Borrelli +2
We address memory effects and diffusive properties of a continuous-time quantum walk on a one-dimensional percolation lattice affected by spatially correlated random telegraph nois…
Ultimate limits for quantum magnetometry via time-continuous measurements
Francesco Albarelli, Matteo A. C. Rossi, Matteo G. A. Paris +1
We address the estimation of the magnetic field B acting on an ensemble of atoms with total spin J subjected to collective transverse noise. By preparing an initial spin coherent s…
Non-Markovianity by undersampling in quantum optical simulators
Matteo A. C. Rossi, Claudia Benedetti, Simone Cialdi +4
We unveil a novel source of non-Markovianity for the dynamics of quantum systems, which appears when the system does not explore the full set of dynamical trajectories in the inter…
Probing deformed quantum commutators
Matteo A. C. Rossi, Tommaso Giani, Matteo G. A. Paris
Quantum gravity theories predict a minimal length at the order of magnitude of the Planck length, under which the concepts of space and time lose every physical meaning. In quantum…
Enhanced estimation of loss in the presence of Kerr nonlinearity
Matteo A. C. Rossi, Francesco Albarelli, Matteo G. A. Paris
We address the characterization of dissipative bosonic channels and show that estimation of the loss rate by Gaussian probes (coherent or squeezed) is improved in the presence of K…
Quantum Cloning by Cellular Automata
G. M. D'Ariano, C. Macchiavello, M. Rossi
We introduce a quantum cellular automaton that achieves approximate phase-covariant cloning of qubits. The automaton is optimized for 1-to-2N economical cloning. The use of the aut…
