摘要
我们讨论了一个二能级原子与光场相互作用系统，在远离共振的情况下，当光子与原子之间发生了动量交换时，通过对光场与原子之间纠缠态的测量。
The interaction of a cold atom with a single mode field is studied. In the case of large detuning, the momentum exchanging between atom and field results in the entanglement of atom and light. As a result, the measurement of momemtum of atom can be accomplished from the measurement of light field.
