Coherent light-matter interactions are often understood in terms of dressed states: states that are a composite of light and matter. Recently, we have made a number of experiments to time-resolve the excitonic dressed states of a single self-assembled InAs quantum dot. We demonstrate the possibility of controlling the composition, and energies of the excitonic dressed states on a picosecond timescale. Furthermore, an experiment illustrating that a Rabi oscillation may be interpreted as a beat between two dressed states was performed.

We have fabricated and optimized triggered sources of entangled photon pairs using self-assembled InAs quantum dots. After optimization, a fidelity to the ideal entangled state of over 90% has been achieved.
