| 摘 要： | 提出了制备势阱中的两离子EPR态的一种方法. 这种方法是基于频率调制的行波光场与囚禁离子的相互作用.这种方法的一个突出优点是所制备的量子态为“暗态”，即自发辐射相消的量子态。另外,讨论了二模压缩运动态（两离子质心模式和呼吸模式）的制备.

| Abstract: | A method for preparation of EPR states of two ions in a trap is proposed.This method is based on modulation of the frequency of the traveling wave light field.A prominent characteristic is that the prepared states are "dark" states,i.e.their generation is companied by cancellation of the emitted fluorescence.In addition,the preparation of two-mode squeezing motional state involving in the center-of-mass and breathing modes of two ions is discussed. |
