与砷化镓中的浅施主结合的电子具有与氢原子类似的轨道能级。使用加州大学圣塔芭芭拉分校自由电子激光器的太赫兹 (THz) 辐射验证了类似于磁场中氢的 1s 和 2p 态之间光学跃迁的偏振选择规则。演示了量子态的偏振选择性相干操纵，并讨论了与量子信息处理方案的相关性。
Electrons bound to shallow donors in GaAs have orbital energy levels analogous to those of the hydrogen atom. The polarization selection rules for optical transitions between the states analogous to the 1s and 2p states of hydrogen in a magnetic field are verified using Terahertz (THz) radiation from the University of California, Santa Barbara Free Electron Laser. A polarization-selective coherent manipulation of the quantum states is demonstrated and the relevance to quantum information processing schemes is discussed.
