Abstract
Measurement of a quantum system provides information concerning the state i n which it was prepared. In this paper we show how the retrodictive formali sm can be used to evaluate the probability associated with any one of a giv en set of preparation events. We illustrate our method by calculating the r etrodictive density operator for a two-level atom coupled to the electromag netic field.
