论文摘要
在量子技术中使用量子系统自由度的旋转程度受到反谐解机制下的环境效应的限制。在这里，我们根据以旋转自由度叠加制备的非球形量子系统的弹性散射的新形式，研究了破坏性的机制。我们表明，对于浸入由热光子组成的环境中的介电椭圆形，旋转的分解速率取决于系统的两种构型与温度的第七功率之间的角度差异，这与翻译的差异不同。然后，我们分析环境球形谐波的角动量量子数的不同值对旋转反应速率的影响。
The use of rotational degrees of freedom of quantum systems in quantum technologies is limited by environmental effects under decoherence mechanism. Here, we study the mechanism of decoherence based on a new formalism of elastic scattering for a nonspherical quantum system prepared in a superposition of rotational degrees of freedom. We show that for a dielectric ellipsoid immersed in an environment composed of thermal photons the rotational decoherence rate depends on the angular differences between the two configurations of the system and the seventh power of the temperature which is different from the translational one. Then we analyze the effect of different values of angular momentum quantum numbers of the environmental spherical harmonics on the rotational decoherence rate.
