I will talk about how recent advancement in the application of quantum information processing techniques to neutron sciences, opened a way to the construction of a neutron interferometry beamline that is compact and less costly, have higher neutron flux and polarization. The setup is designed for perfect crystal neutron interferometry whose operation principles is governed by the theory of dynamical diffraction (DD). I will present an alternative quantum information approach to DD that is based on a repeated application of a unitary operator at a coarse-grained site. Using this formalism, I will show how a new five-blade neutron interferometer design may refocus noise originating for DD and mechanical vibration. Finally, I will look into the possibility of adding more degrees of freedom to a neutron interferometer by discussing the generation and control of orbital angular momentum of a neutron wave packet.
