Oi, Daniel K.L. (2003) Interference of quantum channels. Physical Review Letters, 91 (6). ISSN 0031-9007Full text not available in this repository. (Request a copy from the Strathclyde author)
We show how interferometry can be used to characterize certain aspects of general quantum processes and, in particular, the coherence of completely positive maps. We derive a measure of coherent fidelity, the maximum interference visibility, and the closest unitary operator to a given physical process under this measure.
