Quantum Electronics and Quantum Optics (QEO)
Research Mission
The research at the Laboratory of Quantum Electronics
and Quantum Optics focuses on quantum mechanical
phenomena. We explore the physical limitations of
electronics and optics and try to harness the
opportunities quantum systems offer in information
processing.
Research Overview
As the physical dimensions of the building blocks in
electronics and optics shrink, quantum mechanical effects
become increasingly important. We explore applications of
quantum systems in electronics, optics and information
technology. Some specific areas we have researched in this
respect are microlasers, fibre-optical communication
systems, optical amplifiers, quantum cryptography and
optical and atomic interferometry. In addition we try to
improve our understanding of fundamental quantum physics.
Some examples of such research include complementarity,
measurement back-action, simultaneous measurements and the
physical representation of information.
