在无测量电路中，提出两位纠错量子电路的概念。构造出纠两位错的量子编码方案及量子纠错电路，此电路可以同时纠正量子信息中的一位错、两位错，突破了以往量子电路只能纠正一位错的局限。引入编码电路编码输入信息的辅助位，根据辅助位的不同判断输入信息的不同量子状态。在设计七量子位的纠错电路过程中，提出了模块化思想，以五量子位纠错电路为基础模块构建纠错电路，简化了多量子位纠错电路的设计过程。

Under the non-measuring circuits, it is used the truth table method to propose the concept of two quantum error-correcting circuits and then a circuit which can code and correct one-qubit error、two-qubits error is construeted. This quantum circuit can correct one-qubit error and two-qubits error at the same time, break through the former limit that the circuit can only correct one-qubit error. A coding circuit is recommended to encod auxiliary bits of inputing information and judge the different input-bits quantum states according to different auxiliaries. During the process of designing 7-qubits error correction circuit, a modular thinking is advanced based on the 5-qubits error-correction circuits which can simplify the multi-qubits error-correction circuit design process.
