A qubit device includes first and second linear qubit arrays. Each qubit array includes a semiconductor substrate, control gates configured to define a single row of quantum dots along the substrate, and nanomagnets distributed along the row of quantum dots such that a nanomagnet is arranged at every other pair of quantum dots of the row of quantum dots. Each nanomagnet has an out-of-plane magnetization with respect to the substrate, where the rows of the first and second arrays extend in a common row direction and are separated along a direction transverse to the row direction. The qubit device further includes superconducting resonators connecting pairs of quantum dots between the first and second arrays. Each pair of quantum dots in the first array is configured to couple with a superconducting resonator of the first set to connect with a different pair of quantum dots of the second array.
