Topological insulators are one of the most puzzling quantum materials. Their edges are electron superhighways where electrons flow with no loss, while the bulk of the material blocks electron flow - properties that could be useful in quantum computing and information processing. Researchers used a process called high harmonic generation to separately probe electron behavior in both of those domains. The method should be applicable to a broad range of quantum materials.
