However, conductor resistance is becoming a problem as the line width of interconnects decreases due to higher density. On the other hand, it has recently been proposed to use a superconducting conductor as this conductor.

問題となってくる。Therefore, it is expected that superconducting wiring will replace conventional normal conducting wiring in the future. However, in superconducting interconnects, there is a significant difference in resistance between the superconducting state and the normal conducting state, so once the superconducting state transitions to normal conducting state, the electronic circuit may go out of control or stop working.
