For several years now, multi-photon interfering effects have been at the focus of quantum optical research. The measurement of multi-photon interferences and correlations has a multitude of astounding properties and possible applications. These include, for example, entanglement of particles at a distance, the observation of collective effects, quantum teleportation, so-called ghost imaging, and the possibility to beat the classical resolution limit of a microscope (so-called quantum imaging).
For the first time, multi-photon interferences were observed by Hanbury Brown and Twiss in 1956 to determine the angular diameter of stars (HBT experiment). The complete quantum mechanical description of multi-photon correlations took place a few years later by Roy Glauber (honorary doctorate of FAU), who was awarded the Nobel Prize in 2005 for his contributions to the field of quantum optics. The historical HBT experiment has always been referred to as the birth of quantum optics.
In the group, we conduct basic theoretical research and perform a variety of experiments, e.g., the measurement of temporal and spatial photon correlations within the subject of quantum imaging. In these areas, we are interested in experimental and theoretical work, which can be conducted in the context of Bachelor and Master theses. For instance, we are interested in:
- Measurements of multi-photon interferences using a CCD camera (experiment)
- Measurements of multi-photon interferences to beat the classical resolution limit (experiment)
- Multi-photon correlation measurements to verify the principles of quantum mechanics (experiment)
- Correlation measurements with conventional thermal light sources (experiment)
- Measurement of non-classical photon statistics using so-called SPDC sources (experiment)
- Generation of entangled states for quantum information processing (theory)
- Investigation of measurement-induced cooperative effects in quantum mechanics (theory)
All studies provide good insight into fundamental questions of quantum optics. If your interest is aroused and you want to know more about these topics, do not hesitate to contact us or come to us.
