Quantum Emulation of Molecular Force Fields: A Blueprint for a Superconducting Architecture
Diego González Olivares, Borja Peropadre, Joonsuk Huh, Juan José García‐Ripoll · Physical Review Applied · 2017
Electronic transitions, such as those induced by light, excite a molecule's vibrations in a way that is very difficult to compute. The authors propose a superconducting circuit that can efficiently and robustly simulate these transitions and provide the distribution of vibronic excitations. This single-purpose quantum simulator would consist of microwave resonators, tunable inductors, and superconducting qubits, with realistic conditions for preparation, quench, and measurement. Using the nonlinearities of Josephson junctions, the simulator could also treat the anharmonic regime of vibronic transitions, which is an even harder computational problem.
