Towards realization of protected qubits using topological superconductivity

Javad Shabani

A central goal in quantum computing research is to protect and control quantuminformation from noise. This talk will provide recent progress on the developing field of topological superconductivity where we can encode information in spatially separated Majorana zero modes (MZM). We show that topological superconductivity can be achieved in certain hybrid materials where the topological properties are not found in the constituent materials. These special MZMs are formed at the location of topological defects (e.g. boundaries, domain walls,..) and manifest non-Abelian braiding statistics that can be used in noise-free unitary gate operations. We show by engineering a reconfigurable domain walls on a Josephson junction we can create a scalable platform to study MZM properties and their applications in quantum information science.
