Claim 0:
1. A qubit assembly preparation method 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.
