Information in neutron interference experiments
Abstract
Wigner measures are calculated for a number of neutron interference experiments that can be interpreted as joint nonideal measurements of path and interference. It is demonstrated that the Wigner measure need not be influenced by fluctuations, thus showing that fluctuations need not diminish the information content of the experiment. A measurement is proposed yielding complete information on the incoming neutron state.
