Operator Deformations in Quantum Measurement Theory    [PDF]

Andreas Andersson

In this paper we develop a rigorous observable- and symmetry generator-related framework for quantum measurement theory by applying operator deformation techniques previously used in noncommutative quantum field theory. This enables the conventional observables (represented by unbounded operators) to play a role also in the more general setting. In addition it gives a way of explicitly calculating the so-called instrument of the measurement process.
