本文提出了一种利用囚禁离子的运动产生两个双模SU（2）相干态的叠加方案。在该方案中，离子被捕获在二维各向同性谐振势中，并由两束共振激光驱动。在一定条件下，通过对离子与激光相互作用后的内部态进行条件测量，可以产生运动双模SU（2）猫态。
A scheme is presented for the generation of superpositions of two two-mode SU(2) coherent states of the motion for a trapped ion. In the scheme an ion is trapped in a two-dimensional isotropic harmonic potential and driven by two resonant laser beams. Under certain conditions, the motional two-mode SU(2) cat state can be generated after a conditional measurement on the internal state following the ion-laser interaction.
