Abstract: Superconducting circuits are an excellent platform for quantum simulation, with various protocols enacted using highly coherent transmon qubits in a digital (gate-based) approach. Analog simulations with transmons, though, are typically limited by restrictive intercircuit coupling. The authors propose an alternative strategy based on periodic modulation of an effective magnetic field, enabling a Floquet description of the system. This allows one to modify the existing two-qubit interaction and the effective spin Hamiltonian, without modifying the setup. Detailed analysis shows this Floquet-type simulator to be quite advantageous, outperforming state-of-the-art digital approaches.
