中文摘要：

在无测量状态下，对三量子位纠错电路进行设计和优化，提出模块化概念设计和优化量子纠错电路。随着量子位的增加，三量子位纠错电路作为模块可用于五量子位纠错电路中，五量子位纠错电路作为模块可用于七量子位纠错电路中，以此类推。少量子位纠错电路作为多量子位纠错电路的部分模块使用，可使得多量子位纠错电路设计简化，冗余位减少，使之量子代价较低。

英文摘要：

The 3-qubit error-correction quantum circuit is realized and optimized in the non-measuring condition. The modular thought is presented to design and optimize the quantum error-correction circuit. With the quantum bits increasing, the error-correction circuit of 3-qubits can be used in the error-correction circuit of 5-qubits as a module. The error-correction circuit of 5-qubits can be used in the error-correction circuit of 7-qubits. By parity of reasoning, the error-correction circuit of a few quantum bits can be used in the error-correction circuit of multiple quantum bits. The quantum error-correction circuit can be simplified and the redundant qubits can be reduced using the method. It can also make the quantum cost lower.
