Electron spin relaxation, important in quantum information science, can be slowed down at clock transitions — which are insensitive to magnetic noise. It has now been shown that such transitions can be tuned, to high frequency, in rare-earth coordination complexes through control of s- and d-orbital mixing.

分子自旋时钟

在量子信息科学中很重要的电子自旋弛豫可以在时钟跃迁时减慢——这对磁噪声不敏感。现在已经表明，通过控制 s 和 d 轨道混合，可以在稀土配位配合物中将这种转变调整到高频。
