Abstract
Direct observations of the dynamics of single excitonic quantum dots require the use of transient optical spectroscopy. Measurements of the lifetimes of single QD states, Rabi oscillations, biexciton formation and decay, and the development of quantum logic gates are examples of dynamical effects in quantum dots most easily studied through transient nonlinear spectroscopy, but are extremely challenging at the single dot level. We report here the first observation of transient differential transmission from single quantum dots as well as evidence of Rabi oscillations in single quantum dots.
