Making usable quantum technologies out of rare-earth compounds has remained a challenge because they contain critically radioactive compounds rendering them of limited use in real-world quantum technologies. An international team of researchers (Switzerland, Finland) used the sub-nanometre thickness of graphene to create heavy fermions. By layering thin sheets of carbon on top of one another in a specific pattern, where each sheet is rotated in relation to the other, it is possible to create the quantum properties effect that results in the electrons in the graphene behaving like heavy fermions. While in this work they showed the emergence of heavy fermion behavior, addressing the emergence of topological superconductivity is a natural next step. It could potentially have a groundbreaking impact for topological quantum computing. Their work potentially provides a carbon-based platform for exploitation of heavy fermion phenomena in quantum technologies…read more. TECHNICAL ARTICLE
