Filtering of Wide Sense Stationary Quantum Stochastic Processes
John Gough
We introduce a concept of a quantum wide sense stationary process taking values in a C*-algebra and expected in a sub-algebra. The power spectrum of such a process is defined, in a…

The Series Product and Its Application to Quantum Feedforward and Feedback Networks
J. Gough, M. R. James
The purpose of this paper is to present simple and general algebraic methods for describing series connections in quantum networks. These methods build on and generalize existing m…
