The disclosed qubit device (200) comprises two linear qubit arrays (101, 102), each comprising a semiconductor substrate layer (110), a set of control gates (112, 114, 116) configured to define a single row of electrostatically confined quantum dots (122), each quantum dot (122) being suitable for holding a qubit, and a set of nanomagnets (124) with out-of-plane magnetization distributed along the row of quantum dots such that a nanomagnet is arranged at every other pair of quantum dots (122a). The device further comprises a set (211) of superconducting resonators (210) connecting corresponding pairs of quantum dots (122a, 122b) of the first array (101) and second array (102).
