University of Copenhagen physicists, as part of the University and Microsoft collaboration focused on topological quantum computing, may have unloosed a Gordian knot in quantum computer development. In partnership with researchers from University of Chicago, ETH Zurich, Weizmann Institute of Science, and fellow Microsoft Quantum (Science.ku.dk) Lab collaborators at Purdue University, they have designed and realized a promising building block for supercomputers of the future: a two-dimensional platform for that could lead to quantum bits that are both stable and able to be mass produced.
“Our prototype is a significant first step towards using this type of system to make quantum bits that are protected from disturbances. Right now, we still need some fine-tuning – we can improve the design and materials. But it is a potentially perfect structure,” asserts co-lead author Postdoctoral Fellow Antonio Fornieri.
This breakthrough underscores the productiveness of the deepened collaboration established September of 2017 between the University of Copenhagen and Microsoft. This collaboration has only intensified and expanded with the establishing of Microsoft Quantum Materials Lab Copenhagen just one year after, drawing from talent both the University of Copenhagen, the Technical University of Denmark, and around Europe.
