Classification: CPC H | IPC H

Claim 14:
15. A production line device, comprising:
one or more processors; and
memory storing one or more programs, the one or more programs comprising instructions that, when executed by the one or more processors, cause the production line device to perform operations comprising:
preparing a superconducting circuit layer on a substrate, wherein a material of the superconducting circuit layer is aluminum;
preparing an under bump metallization (UBM) layer on an upper surface of the superconducting circuit layer, a superconducting connection is formed between the UBM layer and the superconducting circuit layer; and a material of the UBM layer is a metal niobium; and
preparing a welding spot on an upper surface of the UBM layer to obtain a qubit assembly configured for a flip-chip superconducting quantum chip, wherein a superconducting electrical connection is formed between the welding spot and the UBM layer.
