本文详细分析了各向同性和各向异性光子晶体环境对参数估计精度的影响,得到一些重要结论。研究发现,量子比特跃迁频率和光子晶体带隙边缘频率之间的失谐量和粒子数N对测量精度有着重要影响:通过调控失谐量,最优测量精度可长时间保持在海森堡极限附近;粒子数N增大时,测量精度可呈现出随之降低的情况。 In this paper, the influence of isotropic and anisotropic photonic crystal environment on the accuracy of parameter estimation is analyzed in detail, and some important conclusions are obtained. It is found that the detuning amount and the number of particles N between the quantum bit transition frequency and the photonic bandgap edge frequency have an important influence on the measurement accuracy. By adjusting the detuning, the optimal measurement accuracy can be kept at the Heisenberg limit for a long time Near; particle size N increases, the measurement accuracy can show a decrease.
