摘要
本文提出一个方案以制备一个被囚禁在谐势阱中的离子质心运动的压缩数态。在本方案中,这个离子受到两个分别调到第一高、低振动边带的激光场和一个与离子共振的激光场的轮流激发。系统最后被制备到运动压缩数态与电子基态的直积。
We propose a scheme for the generation of squeezed number states of the center-of-mass motion of a trapped ion. In the scheme the ion is excited by two laser fields tuned to the first lower and higher vibrational sidebands, and then by one laser tuned to the ion transition in an alternative way. Finally, the system is prepared in the state given by the product of the motional squeezed number state with the ground electronic state.
