Abstract
We investigate the transport and coherence properties of a double quantum dot coupled to a single damped boson mode. The numerical results reveal how the properties of the boson distribution can be steered by altering parameters of the electronic system such as the energy difference between the dots. Quadrature amplitude variances and the Wigner function are employed to illustrate how the state of the boson mode can be controlled by a stationary electron current through the dots.
