Abstract
We discuss the relative effects of selective and nonselective atomic measurements on the “quantum purity” of a single mode field. This is a model for non-unit detection efficiency in a micromaser. We show that the quantum mixing associated with non- selective measurements imposes strong limitations on the detection efficiency that can be tolerated if quantum coherences are to be generated and detected.
