Dephasing of a flux-qubit coupled to a harmonic oscillator
P. Bertet, I. Chiorescu, C. J. P. M Harmans +1
Decoherence in superconducting qubits is known to arise because of a variety of environmental degrees of freedom. In this article, we focus on the influence of thermal fluctuations…
Relaxation and Dephasing in a Flux-qubit
P. Bertet, I. Chiorescu, G. Burkard +4
We report detailed measurements of the relaxation and dephasing time in a flux-qubit measured by a switching DC SQUID. We studied their dependence on the two important circuit bias…
Asymmetry and decoherence in a double-layer persistent-current qubit
Guido Burkard, David P. DiVincenzo, P. Bertet +2
Superconducting circuits fabricated using the widely used shadow evaporation technique can contain unintended junctions which change their quantum dynamics. We discuss a supercondu…
Mesoscopic Spin Tunneling in Molecular Crystals
B. Barbara, I. Chiorescu, R. Giraud +2
The phenomenon of Quantum Tunneling of Mesoscopic Spins is reviewed in the light of the behavior of the archetype of these systems: the molecular complex Mn12-ac. Most observations…
