Abstract

I describe recent work in our group on tomography and coherence control in real-world systems, specifically, multi-photon entangled states and ultracold atoms in optical lattices. Near but imperfect indistinguishability complicates tomography in the former case, while inhomogeneous broadening presents challenges in the latter. I present the current status of our work to overcome both problems, and results on tomography of 3-photon states along with pulse-echo studies of decoherence in optical lattices.
