Superconducting qubit network with controllable nearest neighbor coupling
M. Wallquist, J. Lantz, V. S. Shumeiko +1
We investigate the design and functionality of a network of loop-shaped charge qubits with switchable nearest-neighbor coupling. The qubit coupling is achieved by placing large Jos…
Josephson junction qubit network with current-controlled interaction
J. Lantz, M. Wallquist, V. S. Shumeiko +1
We design and evaluate a scalable charge qubit chain network with controllable current-current coupling of neighbouring qubit loops via local dc-current gates. The network allows c…
Andreev Level Qubit
A. Zazunov, V. S. Shumeiko, E. N. Bratus' +2
We investigate the dynamics of a two-level Andreev bound state system in a transmissive quantum point contact embedded in an rf-SQUID. Coherent coupling of the Andreev levels to th…
Phase dependent multiple Andreev reflections in SNS interferometers
J. Lantz, V. S. Shumeiko, E. Bratus +1
A theory of coherent multiple Andreev reflections (MAR) is developed for superconductor-normal metal-superconductor (SNS) interferometers. We consider a Y-shape normal electron bea…
Nonequilibrium Josephson effect in mesoscopic ballistic multiterminal SNS junctions
P. Samuelsson, J. Lantz, V. S. Shumeiko +1
We present a detailed study of nonequilibrium Josephson currents and conductance in ballistic multiterminal SNS-devices. Nonequilibrium is created by means of quasiparticle injecti…
