Abstract
The large spin-orbit interaction of holes in semiconductors is key to achieving strong spin-photon coupling in spin circuit-QED experiments. Here, the authors show that for a single hole this coupling is ``reciprocally sweet'', meaning that the coupling can be tuned from fully transverse (allowing coherent spin rotations) to fully longitudinal (modulating the spin resonance frequency). Based on the longitudinal coupling, the authors highlight how distant spin-spin coupling and parametrically driven spin readout can be achieved.
