Groups - Institute for Photonic Quantum Systems (PhoQS) | Paderborn University

PhoQS groups and priorities

The PhoQS pools the expertise of scientists, including four ERC grant holders, from four specialist disciplines. The research work of the groups from the disciplines of Physics, Mathematics, Computer Science and Electrical Engineering combines excellent basic research with application-oriented research at the highest level.

Physics

AG Bartley: Mesoscopic quantum optics

The mesoscopic quantum optics (MQO) group tries to expose non-classical phenomena to ever larger energy scales by using light.

AG JProf Güsken: Quantum Photonics & Optoelectronics

We are researching novel platforms in the field of manipulation, detection and transmission of light fields (optoelectronics & nanophotonics). We are also interested in researching active component interfaces with photonic integrated circuits (PIC) and networks as well as the manipulation of integrated quantum emitters.

AG Jöns: Hybrid Quantum Photonic Devices

Our Hybrid Quantum Photonic Devices (hqpd) group focuses on the development of novel devices for photonic quantum technologies, with a particular focus on quantum communication and photonic quantum computing applications.

AG Meier: Computational Optoelectronics and Photonics

We are interested in the optical, electronic and quantum-optical properties of various material systems, which we analyse using microscopic theory and numerical simulations.

AG Reuter: Optoelectronic materials and components

The optoelectronic materials and devices group focuses on the production and characterisation of semiconductor structures for optical and electronic applications, e.g. in quantum information technology.

AG Schumacher: Theory of functional photonic structures

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

AG Silberhorn: Integrated Quantum Optics

The group develops and investigates novel optical devices and methods with regard to applications in quantum information processing, quantum communication and the fundamental understanding of quantum theory.

AG Sperling: Theoretical quantum systems

Motivated by quantum information science and its quantum optical implementations, our goal is to advance the foundations and applications of quantum physics. Our research ties in with neighbouring fields such as experimental physics, mathematics and computer science.

AG Zentgraf: Ultra-fast nanophotonics

The Ultrafast Nanophotonics group focuses on research into the optical properties of artificially created material systems.

Electrical Engineering

AG Förstner: Theoretical Electrical Engineering

Our field of research is the theoretical description of photonic and optoelectronic systems. Our strength lies in the combination of highly developed material models with state-of-the-art numerical methods for the simulation of electromagnetic fields.

AG Scheytt: Circuit technology

Modern nano- and microelectronics make it possible to combine complex digital circuits, analogue circuits and new types of components on a single chip. We are researching a new generation of extremely energy-efficient intelligent systems.

Computer science

AG Blömer: Codes and Cryptography

We develop and analyse cryptographic methods, in particular for the protection of privacy. Our interests range from the complexity-theoretic and algorithmic foundations of cryptographic techniques, the design and proof of the security of cryptographic primitives to their efficient implementation.

AG Gharibian: Quantum Informatics

We work in the research area of theoretical computer science, focussing on quantum algorithms and complexity theory. A main goal of the group is to understand the complexity of low-temperature many-body quantum systems.

Junior Research Group Raissi: Quantum Information

Our research spans a number of topics in quantum theory, including Many-Body Entanglement, Classical and Quantum Error Correcting Codes, Quantum Networks, Quantum Algorithms, and focuses on bridging abstract theory and experimental reality.

Mathematics

Junior Research Group Hinrichs: Mathematical Physics of Complex Quantum Systems

The junior research group deals with mathematical questions that originate in the treatment of quantum theories. Concrete models can be many-body systems or quantum field theories. The mathematical methods used originate from functional analysis (spectral and operator theory) and stochastic analysis.

AG Kolb: Probability theory

The research interests of the Stochastics group centre on the mathematical analysis of systems with random components. There are often references to important methods in statistical analyses such as MCMC methods or to models from statistical physics or quantum mechanics.

AG Weich: Spectral analysis

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