本文提出在量子编码中用量子字节(quantum-byte)控制量子字节的设想,具体分析了字节(2位)被控编码法防止或纠正逻辑运算错误的量子线路.该编码既适用于量子逻辑门的防错和纠错,也适用于防止量子计算机存储单元的解相干.该编码法量子位使用效率为50%,且防错和纠错过程简单明了,并有单个逻辑态双轨(dual-rail)技术提供实验基础,因此该方案实现的可能性大.

A scheme of error prevention and error correction using quantum-byte controlling quantum-byte in quantum logic operation was proposed. It is suitable for quantum logic gate and quantum computer memory. The qubits service efficiency of this encoding method is 50%, and the process of error prevention and error correction is simple and clear. The dual-rail representation of single logical state provides a foundation for the...
