Decoherence in Josephson qubits
G. Falci, E. Paladino, R. Fazio
A high degree of quantum coherence is a crucial requirement for the implementation of quantum logic devices. Solid state nanodevices seem particularly promising from the point of v…
Dynamical suppression of telegraph and 1/f noise due to quantum bistable fluctuator
G. Falci, A. D'Arrigo, A. Mastellone +1
We study dynamical decoupling of a qubit from non gaussian quantum noise due to discrete sources, as bistable fluctuators and 1/f noise. We obtain analytic and numerical results fo…
Interplay between pairing and exchange in small metallic dots
G. Falci, Rosario Fazio, A. Mastellone
We study the effects of the mesoscopic fluctuations on the competition between exchange and pairing interactions in ultrasmall metallic dots when the mean level spacing is comparab…
Mesoscopic fluctuations in superconducting dots at finite temperatures
G. Falci, A. Fubini, A. Mastellone
We study the thermodynamics of ultrasmall metallic grains with the mean level spacing comparable or larger than the pairing correlation energy in the whole range of temperatures. A…
Quantum fluctuations in superconducting dots at finite temperature
G. Falci, A. Fubini
We study the thermodynamics of ultrasmall metallic grains with level spacing comparable or smaller than the pairing correlation energy, at finite temperatures, $T \gsim δ$. We…
The Quantum Dissipative Villain Model
G. Falci, G. Giaquinta, U. Weiss
We introduce the Quantum Dissipative Villain (QDV) model as a prototype model to study tunneling in dissipative quantum mechanics. Dissipation is provided by a coupled linear envir…
