By coupling pairs of superconducting qubits through a small Josephsonjunction with a time-dependent flux bias, we show that arbitrary interactionsinvolving any combination of Pauli matrices can be generated with a smallnumber of drive tones applied through the flux bias of the coupling junction.We then demonstrate that similar (though not fully universal) results can beachieved in capacitively coupled qubits by exploiting the higher energy statesof the devices through multi-photon drive signals applied to the qubits' fluxdegrees of freedom. By using this mechanism to couple a qubit to a detunedresonator, the qubit's rotating frame state can be non-destructively measuredalong any direction on the Bloch sphere. Finally, we describe how thefrequency-converting nature of the couplings can be used to engineer amechanism analogous to dynamic nuclear polarization in NMR systems, capable ofcooling an array of qubits well below the ambient temperature, and outline howhigher order interactions, such as local 3-body terms, can be engineeredthrough the same couplings. Our results demonstrate that a programmable quantumsimulator for large classes of interacting spin models could be engineered withthe same physical hardware.
