| 摘 要： | We propose a quantum nondemolition measurement of the photon-numberdistribution for a weak cavity field with no more than two photons. Thescheme is based on the resonant interaction of atoms with the cavityfield, and thus the required interaction time is much shorter than that using dispersive interaction. This is important in view of decoherence. Our scheme can also be used to generate even and odd coherent states for a weak cavity field with resonant atoms.
