Probabilities and signalling in quantum field theory
Prof. Jeffrey Robert Forshaw (Manchester Univ.)
We present an approach to computing probabilities in quantum field theory for a wide class of source-detector models. The approach works directly with probabilities and not with squared matrix elements, and the resulting probabilities can be written in terms of expectation values of nested commutators and anticommutators. We present results that help in the evaluation …
