Matter and Quantum Systems
This section of the profile is dedicated to the fundamental building blocks of the universe and the central questions: What holds matter together at its core? How did the universe come into being? How can we better understand the principles of quantum theory, such as superposition and entanglement, and apply them to the development of new computer technologies?
This research area combines basic research in elementary particle physics and quantum optics with the goal of answering fundamental questions in physics and developing new quantum information technologies. Theoretical particle physics focuses on advancing quantum field theory and testing the Standard Model. Experimental particle physics seeks, through international collaborations—such as at CERN and DESY—to identify discrepancies between theory and experiment as well as previously unknown particles.
Quantum research also strives—in both theory and experiment—to gain a deep understanding of the fundamentals of modern quantum physics. Furthermore, it utilizes the unique principles of quantum physics—such as the superposition and entanglement of qubits—to develop novel, high-performance computers. The University of Siegen plays a central role in the development of quantum computer technologies and, with its first German startup, is driving forward the development of ion-based quantum computers.
