Quantum simulation has emerged as a powerful framework for investigating complex many – body phenomena. A key requirement for emulating these dynamics is the realization of fully
controllable quantum systems enabling various spin interactions. Yet, quantum simulators remain constrained in the types of attainable interactions. Here we demonstrate experimental realization of multiple microwave – engineered spin interactions in superconducting quantum circuits. By precisely controlling the native XY interaction and microwave drives, we achieve tunable spin Hamiltonians including: (i) XYZ spin models with continuously adjustable parameters, (ii) transverse – field Ising systems, and (iii) Dzyaloshinskii – Moriya interacting systems. Our work expands the toolbox for analogue – digital quantum simulation, enabling exploration of a wide range of exotic quantum spin models.
