Realizing a strong coupling between spin and resonator is an important issue for scalable quantum computation in semiconductor systems. Benefiting from the advantages of spin–orbit strength long coherence time, Ge hut wire, which proposed to be site-controlled grown scalability, considered promising candidate achieve this goal. Here we present hybrid architecture on-chip superconducting microwave coupled holes dot. The charge stability diagram can obtained amplitude phase responses independently DC transport measurement. Furthermore, estimate hole-resonator rate gc/2π = 148 MHz single dot-resonator system spin–resonator gs/2π range 2–4 MHz. We anticipate that hole spins photons wire feasible with optimized schemes future.
