Abstract
A joint device structure for capacitive microwave coupling of a superconducting device arranged on a substrate with room temperature circuitry; including a superconducting wave guide of an oxide superconductor on said substrate from one side to the superconducting device launching microwave to the superconducting device, a pair of superconducting groundplanes of an oxide superconductor arranged at an end of the superconducting wave guide sandwiching the end of the superconducting wave guide with a little gap and a microwave probe-head connected to the room temperature circuitry arranged above the superconducting wave guide with a coupling gap having three probing pins corresponding to the superconducting wave guide and the superconducting groundplanes.
