Induced Superconductivity in the Fractional Quantum Hall Edge in Graphene Heterostructures

Explore cutting-edge research on topological superconductors and their potential applications in quantum computing in this 49-minute lecture by Philip Kim from the PCS Institute for Basic Science. Delve into the world of Majorana modes and parafermions, examining their role in creating topologically protected logic operations and universal quantum gate sets. Learn about the latest advancements in synthesizing parafermions by inducing superconductivity in the fractional quantum Hall (fqH) edge. Discover the groundbreaking experiments using high-quality van der Waals devices coupled with narrow superconducting NbN, demonstrating the coexistence of superconductivity and robust fqH. Analyze the findings on crossed Andreev reflection (CAR) across superconductors separating counterpropagating fqH edges, and understand the implications of spin-orbit coupling in enabling pairing of spin-polarized edges. Gain insights into the contrasting behaviors of integer and fractional quantum Hall edges, and explore the potential of these discoveries in paving the way for experimental research on parafermions in condensed matter physics.
