The effect of Magnetic Field on MQT Escape Time in "Small" Josephson Junctions
Yu. N. Ovchinnikov, A. Barone, A. A. Varlamov
We study the phenomenon of macroscopic quantum tunneling (MQT) in a finite size Josephson junction (JJ) with an externally applied magnetic field. As it is well known, the problem…

Quantum Computation with Aharonov-Bohm Qubits
A. Barone, T. Hakioglu, I. O. Kulik
We analyze the posibility of employing the mesoscopic-nanoscopic ring of a normal metal in a doubly degenerate persistent current state with a third auxihilary level and in the pre…
