Abstract

With the quantum state diffusion measurement theory (QSD), the measurement problem in liquid nuclear magnetic resonance (NMR) quantum computers was addressed and then it was shown that due to stochastical fluctuations, the measured magnetic moment value is comparable to noise for long times. Therefore, we suggested that the measurement time should be short to distinguish signal from noise.

液体核磁共振量子计算机中的测量问题

利用量子态扩散测量理论（QSD）解决了液体核磁共振（NMR）量子计算机中的测量问题，并证明了由于随机波动，测量的磁矩值在很长时间内与噪声相当。因此，我们建议测量时间应短，以区分信号和噪声。核磁共振量子计算机中的QSD。
