Research Summary
We perform research in theoretical condensed matter physics, including quantum information processing, computational physics, transport phenomena, energy conversion and solar energy, as well as the dynamics of complex systems. Our research work is interdisciplinary and also explores the interface between atomic physics, quantum optics, nanoscience, quantum information, and computing. We are also studying optics, nanophotonics, artificial photosynthesis, lighttoelectricity conversion, nanomechanics, hybrid quantum electromechanical systems, quantum nanoelectronics and quantum emulators. Particular emphasis is being placed on superconducting Josephsonjunction qubits, scalable quantum circuitry and improved designs for their quantum control.
