本文详细分析了各向异性光子晶体环境中量子弱测量和测量反转对原子熵压缩的影响,得到一些重要结论。研究发现,量子比特和光子晶体带隙边缘频率之间的失谐量δ以及量子弱测量和测量反转强度对熵压缩起着重要作用,通过调节它们,可以获得更好的熵压缩。

The effects of quantum weak measurement and measurement reversal on the entropy squeezing have been studied in details in the anisotropic photonic crystal environment and some important conclusions have been obtained.It has been showed that both the detuning between the qubit’s transition frequency and the band edge of the photonic crystal and the strengths of weak measurement play a key role in the entropy squeezing.By adjusting them,the optimal entropy squeezing can been got obtained.
