Operational description of a momentum observable — •Fabio Di Pumpo, Hannes Weber, and Matthias Freyberger — Institut für Quantenphysik, Universität Ulm, 89069 Ulm

We present the definition of an operational momentum operator. This definition is motivated by a classical time-of-flight measurement which we model by a Hamiltonian for a particle interacting with two quantum pointers at different times. We solve the corresponding dynamics in the Heisenberg picture. Our aim then is to calculate the optimized bipartite pointer state, so that the statistics of the operational momentum operator resembles the one of the original momentum operator describing the single-particle system.
