旋转单自旋的可测量子几何相位

Measurable quantum geometric phase from a rotating single spin

D. Maclaurin, M. W. Doherty, L. C. L. Hollenberg, A. M. Martin

摘要:

我们证明了一个单一的氮空位缺陷的内部磁状态,在旋转的金刚石晶体,获得几何相位。几何相移表现为磁子态叠加的分量之间的相对相位。我们证明,在合理的实验条件下,相移高达四个弧度可以测量。这样的几何相位的积累的测量,由于宏观旋转,将是第一个单原子尺度的量子系统。

英文摘要:

We demonstrate that the internal magnetic states of a single nitrogen-vacancy defect, within a rotating diamond crystal, acquire geometric phases. The geometric phase shift is manifest as a relative phase between components of a superposition of magnetic substates. We demonstrate that under reasonable experimental conditions a phase shift of up to four radians could be measured. Such a measurement of the accumulation of a geometric phase, due to macroscopic rotation, would be the first for a single atom-scale quantum system.
