Seminar description:

Superconducting circuits have evolved from a toy to study fundamental light-matter interaction into a prime candidate for scalable quantum computing. In addition to university groups, industry has started to enter the field (Goolge, IBM, Microsoft, D-Wave Systems, Rigetti quantum computing etc.). As of 2018, chips with several tens of coherent superconducting qubits have been reported, either as open or commercial platforms. The next big challenges are the demonstration of a quantum advantage and useful quantum error correction.

Within the seminar, students give talks on the latest developments in quantum computing with superconducting circuits and related areas such as spin systems or nanomechanics. The seminar is relevant for the special courses on "Superconductivity and Low Temperature Physics" and "Applied Superconductivity". The seminar is suitable for bachelor and master students in the 6. semester and higher. Seminar talks can be given either in English or in German
