Groups in PhoQS

Our research areas are cryptography and cluster analysis.


We are interested in the optical, electronic, and quantum optical properties of different material systems which we analyze by microscopic theory and numerical simulations.


Our Group Hybrid Quantum Photonic Devices (hqpd)  is engaged in the development of novel devices for photonic quantum technologies, with particular emphasis on quantum communication and photonic quantum computing applications.


The IQO group develops novel optical devices and methods for possible future applications in quantum information processing, quantum communication and for fundamental quantum experiments.


The Mesoscopic Quantum Optics (MQO) group uses light to try and expose nonclassical phenomena at larger and larger energy scales.


The group of Optoelectronic Materials and Devices at the University of Paderborn focuses its research on the fabrication and characterization of semiconductor heterostructures for optical and electronic applications, for instance in quantum-information technology.


Modern nano- and microelectronic technologies allow the combination of complex digital circuits, analogue circuits, and novel devices on a single chip. We conduct research for a new generation of extremely energy efficient intelligent systems.


The group deals with a wide range of analytical problems motivated by spectral geometry, dynamical systems theory, mathematical physics, or representation theory.


Prof. Dr. Jan Sperling

Wir sind ein junges Team von WissenschaftlerInnen in der Quantentheorie. Unsere Forschung ist getrieben von der Neugier, die bunte Vielfalt und wunderbare Komplexität der Quantenphysik zu erforschen.

Our research covers a range of exciting topics in theoretical condensed matter physics and optics. Fields of particular current interest include nonlinear polariton physics in semiconductor microcavities, multi-exciton states and multi-photon transitions in semiconductor quantum dots.



The Ultrafast Nanophotonics Group investigates the optical properties of artificially created material systems.


Probability Theory is a mathematical branch with a huge range of relations to other scientific areas within and outside of mathematics.
