Abstract

The invention provides a quantum circuit and a control method thereof, a superconducting quantum chip and a superconducting quantum computer, and relates to the field of quantum computers, in particular to the technical field of superconducting quantum chips. The quantum circuit comprises a quantum bit and a reading resonant cavity, and the adjustable coupler is configured to be coupled with the quantum bit and the reading resonant cavity. When the quantum bit is initialized based on the reading resonant cavity, the modulation frequency of the adjustable coupler is configured to be equal to the difference between the frequency of the reading resonant cavity and the frequency of the quantum bit.

Description

technical field [0001] The present disclosure relates to the field of quantum computers, in particular to the technical field of superconducting quantum chips, and in particular to a quantum circuit, a method for controlling the quantum circuit, a superconducting quantum chip and a superconducting quantum computer. Background technique [0002] Superconducting quantum computing is currently considered to be the most likely route to achieve a universal quantum computer. In recent years, the number of superconducting qubits has continued to increase, and the decoherence time of superconducting qubits has also continued to improve, which has enhanced the performance of superconducting quantum processors, which have surpassed classical computers in special computing tasks. , experimentally realized the advantages of quantum computing. However, the current performance of superconducting quantum processors is still far from meeting the general needs of the industry, and how to fu...
