Controlling large quantum computing systems presents developers with major technical challenges. As part of his basic research funded by the Austrian Science Fund (FWF), the Tyrolean quantum researcher Wolfgang Lechner came up with the idea of a new type of architecture for quantum computers, in which the complex networking of many qubits – a frequent stumbling block in quantum computing – becomes a thing of the past. The spin-off company ParityQC, where Lechner and his team are applying the technology, has rapidly become a success story.
