We demonstrate experimental techniques for creating and measuring a coherent superposition of two degenerate atomic states with equal amplitudes in metastable neon. Starting from state (3)P(0), we create adiabatically a coherent superposition of the magnetic sublevels M=+/-1 of the state (3)P(2) using a tripod stimulated Raman adiabatic passage scheme. The measurement is based on the coupling of the levels (3)P(2)<-->(3)P(1) by a linearly polarized laser, followed by the detection of the population in the (3)P(2)(M=+/-2) states as a function of the polarization angle of that laser.
我们展示了在亚稳态氖中创建和测量具有相等振幅的两个简并原子态的相干叠加的实验技术。从态(3)P(0)开始，我们使用三脚架受激拉曼绝热通道方案绝热地创建态(3)P(2)的磁子能级M = ±1的相干叠加。测量基于通过线偏振激光使能级(3)P(2)⟷(3)P(1)耦合，然后检测(3)P(2)(M = ±2)态中的粒子数作为该激光偏振角的函数。
