  Topological magnetism has sparked an unprecedented age in quantum
technologies. Marked by twisted spin structures with exotic dynamical modes,
topological magnets have motivated a new generation of spintronic devices which
transcend the limits of conventional semiconductor-based electronics. While
existing material probes have biased studies and device conceptualizations for
thin samples in two dimensions, advancements in three-dimensional probing
techniques using beams of neutrons, are transforming our understanding of
topological and emergent physics to reimagine spintronic devices. Here, we
review recent neutron scattering breakthroughs which harness quantum degrees of
freedom to enable three-dimensional topological investigations of quantum
materials. We discuss applications of structured and tomographic neutron
scattering techniques to topological magnets, with particular emphasis on
magnetic skyrmion systems and their inspired three-dimensional logic device
infrastructures through novel multi-bit encoding and control schemes.
SANS-based dynamic visualizations and coherent manipulations of
three-dimensional topological qubits are proposed using electric field controls
of depth-dependant helicities and spin-orbit tuning of the neutron beam.
Together, these investigations uncover a new world of three-dimensional
topological physics which enhances spintronic devices through a novel set of
structures, dynamics, and controls, unique to three-dimensional systems.
