In a computer or communication device, information is
embodied in some physical
capabilities of such an information processing device are derived from its physical properties. It is known
that if the device is quantum mechanical, i.e., it exploits the physical laws of quantum mechanics, then
its capabilities can exceed those of classical devices. Taking a theoretical physics
our group investigates solid-state systems for quantum information processing
In particular, we investigate single electron spin dynamics and coherence in semiconductor and carbon
nanostructores (quantum dots, quantum wires, etc.) as well as superconducting qubits.
Further research areas include light-matter interactions between solid-state qubits and photons,
optical cavities and the use of cavity quantum electrodynamics for quantum information processing,
and the production, dynamics, and characterization of entanglement in solid-state systems.
We are also working on the theory of quantum computation and quantum information.
