Abstract:

Finding qubit with long coherence times and high controllability is a long-standing goal in quantum information science and condensed matter physics. Spin degree of freedom confined by a superconducting gap has been considered as a new resource for such qubits. In this talk, I will present our recent theoretical and experimental studies on spin-split Andreev states in a semiconducting nanowire Josephson junction performed in collaboration with an experimental group. I provide a theoretical model for the junction which takes into account Rashba spin-orbit coupling in the nanowire containing several transverse subbands, identifying the spin-orbit splitting of Andreev states. The theory allows us to understand the response of the microwave resonator coupled to the junction observed in circuit quantum electrodynamics experiments. Finally, I discuss the possible uses of the Andreev spin states as a new superconducting qubit.
