Symmetry-protected gates of Majorana qubits in a high-temperature superconductor platform

I will first introduce the idea of using non-Abelian anyons for topological quantum computation and then propose a platform for braiding Majorana non-Abelian anyons based on a heterostructure between a high-temperature superconductor and a quantum spin-Hall insulator. We show that upon applying a magnetic field in the corner region, two Majorana modes can be manipulated for braiding processes by tuning the field. We show that such a setup can achieve full braiding, exchanging, and a long-sought-after Magic gate of the Majorana zero modes, all of which are robust and protected by symmetries. As many of the ingredients of our proposed platform have been realized in recent experiments, our results provides a new route toward topological quantum computation.
