Discovery of the Chiral Majorana Fermion and Its Application to Topological Quantum Computing

Explore the groundbreaking discovery of the chiral Majorana fermion in this 45-minute lecture by Shoucheng Zhang from Stanford University at the Fred Kavli Special Symposium, APS March Meeting 2018. Delve into the theoretical prediction and experimental realization of this elusive particle in a hybrid structure of quantum anomalous Hall thin film coupled with a conventional superconductor. Learn about the half-integer quantized conductance plateau as a compelling signature of the chiral Majorana fermion and its recent observation in magnetically doped topological insulator coupled with Nb superconductor. Discover a new proposal for braiding chiral Majorana fermions in a Corbino device geometry and understand the implications of this discovery for topological quantum computing, potentially offering significant speed advantages over Majorana zero modes.
