In this talk, I will describe the technique of entangled neutron scattering, which produces a beam of intra-particle entangled neutrons. Neutrons are fantastic candidates for probes to extract information from both mundane and exotic condensed matter systems. For traditional probes, the direct measurement of quantum entanglement within complex materials remains elusive. Often this entanglement is thought to be at the root of the underlying microscopic mechanisms that give rise to remarkable phenomena such as emergent chirality in spin liquids, topological quantum order, and unconventional superconductivity. We suspect that scattering signatures from this entangled probe will help unveil these mysterious mechanics. The entangled neutron scattering group at IU has already demonstrated the entanglement of bipartite (spin-path) and tripartite (spin-path-energy) neutrons through the violation of the CHSH inequality.
