Superconduction refers to a state in which electricity flows through a conductor with no resistance whatsoever. In the case of many superconducting materials however this is only possible at very low temperatures close to absolute zero. Thanks to modern cryostats, which are essentially very powerful refrigerators, such temperatures can in the meantime be achieved with a reasonable amount of effort. Superconductors can be used to build circuits which behave quite similarly to atoms. The states of these artificial atoms can then be manipulated and read out electrically using microwaves. Superconducting qubits recently earned a certain reputation: They were the first technological platform on which the speed advantages of quantum computers could demonstrated in an experiment (based on a highly academic objective).

At its Munich and Regensburg sites in particular, Infineon is working together with the Walther Meißner Institute (WMI) of the Bavarian Academy of Sciences and Humanities, and the Finnish startup IQM, among others, to use superconducting circuits for quantum computing.
