Quantum Dynamical Systems

Our group has worked on theoretical analyses and experimental characterizations of quantum nonlinear dynamics, largely in the context of cavity QED with strong coupling. We have also begun to study information dynamics in quantum nonlinear systems, with a view towards developing broader computational abstractions for quantum engineering. A key aspect of our approach has been to use insights from quantum probability and quantum stochastic processes to develop models of information dynamics beyond the scope of traditional statistical mechanics.
