Physicists isolate bound states in graphene-superconductor junctions

Researchers have documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene. When sandwiched between superconductors, graphene can adopt superconducting capacity because paired electrons from the superconductor are translated to Andreev bound states (ABS) in the graphene. The researchers isolated and manipulated individual ABS by confining them to a graphene quantum dot, which could be used as a qubit for quantum computing.
