abstract = "We review a comprehensive study of the ultrafast optoelectronic properties of a single self-assembled InGaAs/GaAs quantum dot. While manipulation of the artificial atom relies on two widely and independently tunable picoseconds pulse trains, sensitive readout is achieved via the ~pA photocurrent of the diode device. In particular, the absorption changes after occupation of an s-shell exciton reveal a biexciton absorption line as well as previously unobserved p-shell transitions in the presence of s-shell population. In addition, time-resolved data directly maps the picosecond tunneling times of electrons and holes out of the dot. Beyond these incoherent phenomena, we also realize coherent QD manipulations. Those comprise well-known excitonic Rabi-oscillations as well as single-pulse biexciton generation and conditional Rabi-oscillations of the exciton-biexciton transition after deterministic exciton preparation.",
