Neutron interferometry (NI) is the most precise method of characterizing neutron interactions. Interferometry measures the change of the quantum phase of the neutron wave function and can be far more sensitive than cross-section based measurements such as neutron scattering. The primary mission of the Neutron Interferometry and Optics Facility at the NIST Center for Neutron Research (NCNR) is to provide researchers a versatile and state-of-the-art platform to perform both polarized and unpolarized neutron interferometry experiments. The experiments that have been performed encompass a broad range in quantum mechanics, nuclear physics, condensed matter physics, and in quantum information processing. Neutron interferometry-based phase contrast imaging experiments can also be performed at this facility. The low neutron and gamma background rates are ideal for very-high-precision measurements. The neutron interferometer can be an ideal test-bed for new developments in quantum information processing as it provides a powerful example of macroscopic quantum coherence. Quantum information processing codes enable the development of more robust interferometers that can utilize a much larger selection of the neutron phase space distribution and therefore dramatically improve the overall intensity and selection of experiments that can be performed. Research focuses on applications to spintronics and soft matter, quantum coherence, magnetic materials, study of thin films and membranes, and experiments related to inertial and gravitational sensing.
