Research type:
Walther Group
Quantum Information Sciences and Quantum Computation
Our research combines the development of scalable photonic quantum technology for quantum computing and other quantum information applications with the investigation of fundamental quantum science questions. The main activities range from quantum control of single photons using solid-state photon sources, integrated waveguide technology, tailored nonlinear media and detectors based on superconductor technology to interferometric precision measurements of weak gravitational forces.

Quantum Optics, Quantum Nanophysics and Quantum Information
The group is internationally highly competitive in various quantum research areas. These cover experimental and theoretical research in foundations of quantum physics, quantum optics, quantum information, strongly correlated quantum systems as well as molecular quantum nanophysics.
The experimental groups (Markus Arndt, Markus Aspelmeyer, Thomas Juffmann, Nikolai Kiesel, Philip Walther and Anton Zeilinger) run more than a dozen state-of-the-art laboratories on topics related to the foundations of quantum physics, quantum physics with photons, molecules, clusters, nanoparticles and nano-mechanical systems, as well as quantum information processing in computation, simulation, and communication, and optical precision measurements.
The theoretical groups (Časlav Brukner, Borivoje Dakić, Beatrix Hiesmayr, Andreas Nunnenkamp and Norbert Schuch) focus their research on quantum foundations and quantum information theory, relativistic quantum information and metrology, as well as many-body quantum theory.
The group participates in and coordinates a large number of national and international research projects. Group members have been awarded several excellence grants funded by the Austrian Science Fund FWF (START, Wittgenstein, SFB BeyondC) and the European Research Council ERC (Advanced Grants, Consolidator Grants, Starting Grants).
The group’s scientific standing attracts excellent national and international bachelor, master and PhD students who contribute significantly to the group’s high research output as can be seen from the many publications in high-quality and high-visibility journals indexed in scientific databases, including top-rated ones such as Nature, Science or Physical Review Letters.
The close network with the international research community is strengthened by international guest scientists who give lecture courses and presentations for the members of the group on a regular basis.
