Recently, hopping driving scheme that operates at low magnetic fields and low bandwidths has been proposed for silicon spin qubits. In this scheme, novel micromagnet design guidelines are required as the angular difference between the quantization axes of quantum dots becomes crucial for spin driving. In this study, we conducted numerical simulations using a microscopic model describing wave function transitions in continuous space to design micromagnets suitable for this hopping operation.
