Advances in Quantum Detection

Part of the The Springer International Series in Engineering and Computer Science book series (SECS, volume 712)


Some communication links, notably optical channels operating at very low power, are best modeled using quantum mechanics. Quantum signals are not described by stochastic processes, so that the classical theory of detection must be modified to deal with “quantum states”. Interest in such problems has risen in recent years due to the increasing attention on quantum information processing in general. This chapter reviews the basic mathematical formalism of quantum detection, and discusses several existing approaches to detector design. Both the Bayesian theory developed in the 70’s and more recent techniques are considered.
