本文报道了Be-9（+）离子在简谐束缚下的热态、Fock态、相干态和压缩态运动。最后三个状态是从一个离子相干准备的，该离子最初被激光冷却到运动的零点。离子被困在制度，其运动和内部状态之间的耦合，由于应用（经典）辐射，可以描述由Jaynes-Cummings型相互作用。通过这种耦合，内部原子态的演化提供了运动的数态分布的特征。
We report the creation of thermal, Fock, coherent, and squeezed states of motion of a harmonically bound Be-9(+) ion. The last three states are coherently prepared from an ion which has been initially laser cooled to the zero point of motion. The ion is trapped in the regime where the coupling between its motional and internal states, due to applied (classical) radiation, can be described by a Jaynes-Cummings-type interaction. With this coupling, the evolution of the internal atomic state provides a signature of the number state distribution of the motion.
