Abstract

The invention provides a multi-bit control system and method based on superconducting quantum computing. The method comprises the following steps: outputing an initial quantum state and an initial microwave sequence as cross-frequency signals; controlling a built-in multi-bit gate according to the received cross-frequency signals, and outputting a quantum state to be measured; measuring the quantum state to be measured to obtain an inherent fidelity of the current multi-bit gate; and performing computing according to the inherent fidelity to generate an optimized microwave sequence, and performing feedback and optimization on the optimized microwave sequence to obtain a target multi-bit gate.

Description

technical field [0001] The present application relates to the technical field of quantum communication, in particular to a multi-bit control system and method based on superconducting quantum computing. Background technique [0002] Superconducting quantum computing is one of the mainstream implementation methods of quantum computers at present. It uses the quantum characteristics of Josephson junction circuits to encode, and manipulates these qubits (Qubits) according to the laws of quantum mechanics. In this process, the control of qubits is particularly critical, because the control of qubits will directly affect the speed and accuracy of quantum computers. Therefore, how to quickly and accurately control multi-bit gates is crucial to the realization of universal quantum computers is of great significance. [0003] At present, it has been proved that the quantum universal logic gate group can only be composed of one-bit quantum gates and classical two-bit gates. The exis...
