Norbert Lutkenhaus

Professor Lütkenhaus' research group explores the interface between quantum communication theory and quantum optical implementations. They translate between abstract protocols (described by qubits) and physical implementations (described for example by laser pulses); they benchmark implementations to properly characterize quantum advantage and exploit quantum mechanical structures for use in quantum communication.
