| Research Abstract |
We have developed a theory of the quantum transport phenomena in high-Tc superconductor/ferromagnetic insulator Josephson junction and found the formation of the pi-junction in such systems. Based on this peculiar result, we have also proposed a coherent quantum bit using such hybrid systems.
