Abstract：
We propose a quantum nondemolition (QND) measurement of the atomic inversion number of collective atoms confined in a cavity in the context of cavity QED. After a perfect QND measurement the atomic system reduces to a Dick state. We also show how we can generate various nonclassical atomic states. (C) 1998 Elsevier Science B.V. All rights reserved.
