Adiabatic quantum computation with flux qubits, first experimental results
S. H. W. van der Ploeg, A. Izmalkov, M. Grajcar +10
Controllable adiabatic evolution of a multi-qubit system can be used for adiabatic quantum computation (AQC). This evolution ends at a configuration where the Hamiltonian of the sy…
Quasiclassical calculation of spontaneous current in restricted geometries
M. H. S. Amin, M. Coury, A. M. Zagoskin +2
Calculation of current and order parameter distribution in inhomogeneous superconductors is often based on a self-consistent solution of Eilenberger equations for quasiclassical Gr…
DC SQUID based on the mesoscopic multiterminal Josephson junction
M. H. S. Amin, A. N. Omelyanchouk, A. M. Zagoskin
A theory is offered for a novel device, mesoscopic four-terminal SQUID. The studied system consists of a mesoscopic four-terminal junction, one pair of terminals of which is incorp…
Mesoscopic multiterminal Josephson structures: I. Effects of nonlocal weak coupling
M. H. S. Amin, A. N. Omelyanchouk, A. M. Zagoskin
We investigate nonlocal coherent transport in ballistic four-terminal Josephson structures (where bulk superconductors (terminals) are connected through a clean normal layer, e.g.,…
Multi-Terminal Superconducting Phase Qubit
M. H. S. Amin, A. N. Omelyanchouk, A. Blais +4
Mesoscopic multi-terminal Josephson junctions are novel devices that provide weak coupling between several bulk superconductors through a common normal layer. Because of the nonloc…
