In the department of Theoretical Quantum Physics, we explore and simulate quantum systems for the development and enhancement of quantum technologies.
We concentrate on the dynamics of quantum waves to construct novel measuring devices such as matter-wave interferometers. They can, for instance, be employed as precise sensors for rotations and accelerations. In the future, these devices will also be exploited to answer fundamental questions in the search for ultralight dark matter or for the detection of gravitational waves. By modelling degenerate quantum gases in microgravity, we also offer theoretical support for the project BECCAL. In addition, the use of quantum features of photons in a quantum radar or for quantum communication with spacecrafts is an important research priority of the department.
Beyond that, we explore, improve, and employ quantum computers. In order to speed up the solution of real-world problems, we combine quantum algorithms with the method of reinforcement learning. Moreover, we investigate novel quantum computing architectures and implement quantum algorithms on a quantum computer to simulate chemical processes.
