Design and optimization of quantum error-correction circuit with module

Abstract

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
