Title:
QUANTUM BIT FREQUENCY ARRANGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/142386
Kind Code:
A1
Abstract:
Provided in the present disclosure is a quantum bit frequency arrangement method. A quantum bit operating frequency is set in a superconducting quantum bit system to realize a high-fidelity alternating-current CZ gate, and the superconducting quantum bit system comprises a plurality of quantum bits and quantum coupling units which are located between adjacent quantum bits. The quantum bit frequency arrangement method comprises: obtaining energy level structure parameters of superconducting quantum bits according to formant information of quantum bits; constructing an assessment function by means of the energy level structure parameters, so as to quantitatively assess advantages and disadvantages of a quantum bit energy level arrangement solution during multi-bit expansion; and determining, according to the assessment function, a bit operating frequency which avoids a frequency conflict.
