Quantum Bit Behavior of Pinned Fluxes on Volume Defects in a Superconductor

H. B. Lee, G. C. Kim, Byeong-Joo Kim +2

We studied a qubit based on flux-pinning effects in $\Delta$H=$\Delta$B region of a superconductor. When volume defects are many enough in a superconductor, $\Delta$H=$\Delta$B region on M-H curve is…
