When both superconductivity and magnetism coexist, Yu-Shiba-Rusinov states emerge, which can be used as building blocks to promote Majorana modes suitable for topological quantum computing. We make graphene superconducting with Pb islands (blue triangles). At the same time, we introduce magnetic moments using naturally existing graphene grain boundaries (outlined by arrows). Our experiments show that when both superconductivity and magnetism coexist in graphene, exotic Yu-Shiba-Rusinov states emerge.
