Title:
TEST STRUCTURE FOR SUPERCONDUCTING QUANTUM CHIP AND TEST METHOD FOR SUPERCONDUCTING QUANTUM CHIP
Document Type and Number:
WIPO Patent Application WO/2024/032484
Kind Code:
A1
Abstract:
A test structure for a superconducting quantum chip and a test method for a superconducting quantum chip. The test structure comprises: a reference resonant element (201), which has a first designed resonant frequency; a tested resonant element (202, 202a), which is provided with a first element (103) and a second element (104) that are configured to be connected by means of a first interconnection structure (102) and to be located on different planes, wherein the tested resonant element (202, 202a) is configured on the basis of design parameters, and the design parameters are preset according to the first designed resonant frequency; and a first electrical element (203), which is independently coupled to the reference resonant element (201) and the first element (103) of the tested resonant element (202, 202a), respectively. In the present application, a reference resonant element (201) is introduced into a test structure as the contrast of a tested resonant element (202, 202a), the reference resonant element (201) is also coupled to a first electrical element (203), and has a preset relationship with the tested resonant element (202, 202a) in terms of a resonant frequency; therefore, the relationship between measurement results of the reference resonant element (201) and the tested resonant element (202, 202a) can effectively reflect the on-off performance or connectivity of the tested resonant element (202, 202a).
