    "abstract": "Spin state detection is a key but very challenging step for any spin-based\nsolid-state quantum computing technology. In fullerene based quantum computer\ntechnologies, we here propose to detect the single spin inside a fullerene by\ntransferring the quantum information from the endohedral spin to the ground\nstates of a molecular nanomagnet Fe$_{8}$, with large spin S=10. We show how to\nperform the required SWAP operation and how to read out the information through\nstate-of-the-art techniques such as micro-SQUID.",
