ABSTRACT:
A superconducting system that includes an interface circuit capable of making the best use of a high-speed superconducting circuit and a high-speed semiconductor circuit. A multi-chip module in which an Nb superconducting circuit having Josephson junctions formed by the use of Nb and an oxide high-temperature superconducting latch interface circuit having Josephson junctions formed by the use of an oxide high-temperature superconductor are connected is located in a low temperature environment kept at 4.2 K. The oxide high-temperature superconducting latch interface circuit is connected to a high-speed semiconductor amplifier and a signal outputted from the Nb superconducting circuit is transmitted to the high-speed semiconductor amplifier. As a result, the limit of the operation speed of the oxide high-temperature superconducting latch interface circuit is raised and the superconducting system including the interface circuit capable of making the best use of both the high-speed Nb superconducting circuit and the high-speed semiconductor amplifier is realized.
