Quantum network and other issues
Quantum entanglement lies at the heart of many quantum information processors. It is still an open question how one could share or generate large-scale quantum networks of remote stationary qubits efficiently. Many of these remote quantum entanglements rely on scattering between flying qubits like photons or electrons from matter qubits like atoms or molecules. Our group is interested in various issues related to entanglement ranging from distributed quantum computation to measurement-based quantum computation to quantum metrology and hybrid quantum systems. Members of the group are also involved in quantum simulations, quantum state transfer and the investigation of open quantum systems.
