Master Equation for Retrodiction of Quantum Communication Signals
Stephen M. Barnett, David T. Pegg, John Jeffers +1
We derive the master equation that governs the evolution of the measured state backwards in time in an open system. This allows us to determine probabilities for a given set of pre…
Atomic Retrodiction
Stephen M. Barnett, David T. Pegg, John Jeffers +1
Measurement of a quantum system provides information concerning the state in which it was prepared. In this paper we show how the retrodictive formalism can be used to evaluate the…
Bayes' theorem and quantum retrodiction
Stephen M. Barnett, David T. Pegg, John Jeffers
We derive on the basis of Bayes' theorem a simple but general expression for the retrodicted premeasurement state associated with the result of any measurement. The retrodictive de…
