  In this work, we propose a flexible architecture of microwave resonators with
tunable couplings to perform quantum simulations of problems from the field of
molecular chemistry. The architecture builds on the experience of the D-Wave
design, working with nearly harmonic circuits instead of qubits. This
architecture, or modifications of it, can be used to emulate molecular
processes such as vibronic transitions. Furthermore, we discuss several aspects
of these emulations, such as dynamical ranges of the physical parameters,
quenching times necessary for diabaticity, and, finally, the possibility of
implementing anharmonic corrections to the force fields by exploiting certain
nonlinear features of superconducting devices.
