Abstract: Improved quantum transducers based on ensembles of quantum emitters are provided. This work improves the efficiencies of such transducers by compensating for the detrimental effects of inhomogeneous broadening of transition frequencies in such systems. This approach is built upon the insight that the temporal shape of the drive supplying the energy required for transduction can be experimentally tuned. Hence, it is an additional degree of freedom for designing efficient transducers. We pose the design of the drive as a scattering theory optimization problem, where the transduction efficiency is the quantity being maximized, and employ numerical optimization techniques to solve it.
