Numerical study of induced vortex tunneling
C. D. Bass, S. Khlebnikov
Tunneling of vortex-antivortex pairs across a superconducting film can be controlled via inductive coupling of the film to an external circuit. We study this process numerically in…
Induced vortex tunneling in a superconducting wire
S. Khlebnikov
We consider induced topological transitions in a wire made from cylindrical superconducting film. During a transition, a pulse of electric current causes transport of a virtual vor…
Decoherence in a superconducting ring
S. Khlebnikov
A superconducting ring has different sectors of states corresponding to different values of the trapped magnetic flux; this multitude of states can be used for quantum information…
Thermal fluctuations in macroscopic quantum memory
S. Khlebnikov
We describe macroscopic quantum memory devices based on type-II toroidal superconductors and estimate in one case and compute in another the rates at which quantum information stor…
