The group led by Prof. Alexey Ustinov is located at the university campus of KIT and has a long successful record of exploring the physics of superconducting circuits, both classical and quantum. We are using superconducting qubits for state-of-the-art experiments, challenge new physics questions and explore opportunities for the next generation of quantum information processing. Our group pioneered frequency domain multiplexing readout of qubits, detection and manipulation of microscopic two-level defects, and studied qubit arrays as quantum metamaterials. Our labs are equipped with 6 dilution refrigerators and microwave and mm-wave measurement facilities. We have full access to the in-house cleanroom located next to the lab at Nanostructure Service Laboratory / KIT.
