Title:
METHOD FOR ACHIEVING DOUBLE-BIT QUANTUM GATE ON BASIS OF SUPERCONDUCTING QUANTUM COUPLER
Document Type and Number:
WIPO Patent Application WO/2023/142324
Kind Code:
A1
Abstract:
The present invention provides a method for achieving a double-bit quantum gate on the basis of a superconducting quantum coupler. The superconducting quantum coupler comprises two quantum bits and a quantum coupling unit located between the two quantum bits. The method comprises: improving forward coupling strength between the two quantum bits; increasing the maximum eigenfrequency of the quantum coupling unit; adjusting circuit parameters of the quantum coupling unit such that the frequency of the quantum coupling unit and the frequencies of the quantum bits are always kept above a set detuning amount; and achieving a double-bit quantum gate by applying a current pulse to the quantum coupling unit.
