Circuit quantum electrodynamics, in which microwave cavity modes are coupled to “artificial atoms” realized with Josephson junction qubits, has allowed for a variety of investigations in quantum optics and quantum information. In recent years, our team at Yale has focused on a hardware efficient approach, where high-Q microwave cavities serve as quantum memories. When dispersively coupled to transmon qubits, quite complex non-classical states can be created in these cavities, and operations between cavities can be enacted through parametric driving or other means. For instance, we have recently shown high-quality cavity-cavity swaps via a beam-splitter or conversion operation, single and two-mode squeezing, and engineered cross and self Kerr interactions. Finally, one can perform strong projective measurements of the photon number, the photon parity, or indeed any other binary-valued operator within the multi-dimensional Hilbert space. This system therefore has all of capabilities of linear optical systems, but with the addition of deterministic state preparation, measurement, and nonlinear interactions. One way to employ these capabilities is to directly simulate problems which are “naturally” bosonic in nature, to calculate vibronic spectra, Franck-Condon factors, or nonlinear molecular dynamics. I will present preliminary work towards using this platform as a novel but programmable simulator for small molecules.
