"more reliable intrinsically stable... easily mass-produced... hybrid spin qubits in semiconductors and transmon qubits in superconducting circuits... directly manipulate the spin of the qubit using a microwave signal... high Rabi frequencies embedded within superconducting transmon qubit which enables fast measurement of the qubit state... longevity affected by magnetic field from the surrounding materials... direct strong coupling between spin qubit and superconducting qubit"
