Abstract: Recent developments in quantum technology mean that is it now possible tomanipulate systems and measure fermion fields e.g. reservoirs of electrons atthe quantum level. This progress has motivated some recent work on filteringtheory for quantum systems driven by fermion fields by Korotkov, Milburn andothers. The purpose of this paper is to develop fermion filtering theory usingthe fermion quantum stochastic calculus. We explain that this approach hasclose connections to the classical filtering theory that is a fundamental partof the systems and control theory that has developed over the past 50 years.
