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。

Abstract:

The 3-qubit error-correction quantum circuit is realized and optimized in the non-measuring condition. And 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 reduce using the method. It also can make the quantum cost lower.

Key words: quantum optics, quantum error-correction, modulation, redundancy qubits
