Recent theoretical studies have predicted a number of topologically ordered states of matter that can appear in bulk crystalline materials. I will talk about X-ray photoemission measurements that have been used to identify the first known instances of topological states termed the topological insulator (TI), topological superconductor (TSC), and topological crystalline insulator (TCI). The presentation will review some current ideas about how these states of matter can potentially enable new technologies, how they are experimentally identified, and why they have hidden in plain sight in materials that were already widely studied. I will conclude by discussing possibilities enabled by new X-ray technologies, including an experimental frontier in which quantum topologies can be custom-created by manipulating materials with resonance-tuned X-rays.
