摘要：

Cold Cs atoms are cooled into the ground state (n = 0) of a far detuned 1D optical lattice. From this state, we prepare and detect several quantum states of motion. First, we produce squeezed states of n = 0 (and n = 1) and record the time evolution of the velocity distribution of these states. A velocity distribution compressed by a factor of 4 compared to that of the ground state is obtained. Second, we prepare a linear superposition of n = 0 and n = 1 and observe its time evolution.
