There is great excitement in the condensed matter physics and quantum information technology about using topology to preserve the coherence of a quantum system. If realized, this could replace some of the quantum error correction circuitry needed to sustain coherence in multi-qubit systems and thereby greatly facilitiate quantum computing. Controlling topological structures in condensed matter systems is only at it’s beginning, and it will be physics research for at least a few more years, before it turns into engineering or technology. 
In this talk, I review recent progress by our group and others toward the goal of creating, controlling, and detecting Majorana zero modes in quantum wire, arguably the simplest experimental scheme for generating particles that can encode quantum information in a topological form.
