量子参数估计中的基本理论--量子Cramér-Rao不等式指出,参数估计的方差由量子Fisher信息的倒数决定,量子Fisher信息越大,参数估计的方差就越小,估计精度也就会越高.在非相对论量子力学中,量子Fisher信息已被广泛研究,但考虑相对论效应对量子Fisher信息影响的研究相对较少.本文采用粒子态的相对论变换方法,数值计算和分析了运动参考系中单粒子态、双粒子态振幅参数θ和相位参数φ的量子Fisher信息.结果表明,在运动参考系中,无论是使用单粒子态还是双粒子态,量子Fisher信息都会降低.对于相位参数,双粒子态的量子Fisher信息比单粒子态降低得更加显著.然而,对于振幅参数,双粒子态的量子Fisher信息相对于单粒子态有所提高,该研究结果为在相对论效应的影响下提高参数估计精度提供了有价值的参考.
