  "abstract": "In this work, we explore a hybrid qubit device where quantum information is encoded by quantum states of a transmon entangled with the spin of a trapped Andreev quasiparticle. We term such devices spinmons. We lift the spinmon Kramers degeneracy by introducing a Zeeman field and develop two routes for full qubit control via electrostatic gates and an AC flux drive, providing multiple directions for experimental implementations. Finally, we compute coherence times, verify the qubit robustness against flux, charge and gate voltage noise sources, and discuss the role of nuclear spin noise.",
