Engineering New Qubits with Graphene Nanoribbons
Design for a topological spin qubit within a graphene nanoribbon
Design for a topological spin qubit within a graphene nanoribbon
Graphene nanoribbons (GNRs) are a promising new material that may find use in future quantum computing applications. Derived from graphene lattices, these one-dimensional materials can be designed atom-by-atom using synthetic chemistry approaches. Our research program aims to address the question: can GNRs host a new type of spin qubit? These systems provide high isotopic purity and intrinsic spin-orbit coupling, similar to silicon-based spin qubits. When combined with the unique electrical gating and sensing capabilities from materials such as LaAlO3/SrTiO3 nanostructures, graphene, and silicon host materials.
