Neutron interferometry (NI) with its ability to encode and extract information provides an important probe of matter and precise measurement of physical quantities of vital importance in physics. However, this significant key investigative technique is weakened by its very fragile nature and proven to be highly sensitive to environmental noise. Once brought to its optimal state, the use of neutron interferometry enabled with quantum information, represents a milestone. This talk discusses how to incorporate, into neutron interferometry, two theoretical techniques developed for quantum information sciences, namely, the techniques of quantum error correction and open quantum system. Finally, it briefly presents a method to realize structured waves such as orbital and spin-orbit states of neutrons. Such structured states may be prepared for the beam as a whole, or with reference to the coherence length of the neutron wavepacket and can be used to probe topological materials including skyrmions.
