摘要:

基于近年来光与原子量子界面的多程方法,我们考虑了如何测量原子系综的集体自旋态。我们发现,一个光脉冲两次通过原子系综的方案可以有效地实现自旋态的零差层析。因此,我们建议利用光脉冲作为相移器,旋转自旋的正交。这种方法大大简化了实验方案的几何形状。

英文摘要:

We consider how to measure collective spin states of an atomic ensemble based on the recent multi-pass approaches for quantum interface between light and atoms. We find that a scheme with two passages of a light pulse through the atomic ensemble is efficient to implement the homodyne tomography of the spin state. Thereby, we propose to utilize optical pulses as a phase-shifter that rotates the quadrature of the spins. This method substantially simplifies the geometry of experimental schemes.
