Approximating Vibronic Spectroscopy with Imperfect Quantum Optics. (arXiv:1710.08655v3 [quant-ph] UPDATED)

We study the impact of experimental imperfections on a recently proposed
protocol for performing quantum simulations of vibronic spectroscopy.
Specifically, we propose a method for quantifying the impact of these
imperfections, optimizing an experiment to account for them, and benchmarking
the results against a classical simulation method. We illustrate our findings
using a proof of principle experimental simulation of part of the vibronic
spectrum of tropolone. Our findings will inform the design of future
experiments aiming to simulate the spectra of large molecules beyond the reach
of current classical computers.
