How much information do ultrafast spectra contain? The case for ultrafast quantum process tomography*

In this talk, I will describe the concept of quantum process tomography (QPT). The QPT protocol is a novel way of thinking about ultrafast spectra that allows to design families of experiments for extracting the quantum dynamical map of any system addressable by ultrafast spectroscopy. I will explain how QPT works, and also will describe our progress towards an experimental realization in collaboration with the group of Keith Nelson (MIT).
