论文摘要
我们报告了哑光和四极核之间量子相干性的第一个例子。我们观察到采用A15晶体结构的金钒间化合物中的这种作用，其成员包括所有技术主导的超导体。纠缠状态对局部结构和电子环境极为敏感，该环境通过四极核的电场梯度。这个案例研究表明，即使在没有磁性的情况下，也可以将阳性兆子用作材料中结构和电荷相关现象的量子传感工具。
We report on the first example of quantum coherence between the spins of muons and quadrupolar nuclei. We observe this effect in vanadium intermetallic compounds which adopt the A15 crystal structure, and whose members include all technologically dominant superconductors. The entangled states are extremely sensitive to the local structural and electronic environments through the electric field gradient at the quadrupolar nuclei. This case-study demonstrates that positive muons can be used as a quantum sensing tool to probe also structural and charge related phenomena in materials, even in the absence of magnetic order.
