Gate-defined quantum dots in Si-Ge heterostructures are promising candidates for realizing qubits in quantum processors. We will develop novel k⋅p models for the electronic states in Si-Ge based qubits, and establish an expertise network for quantum technological devices comprised of researchers in mathematics and semiconductor physics within Berlin.
The Workshop “Computing the Electronic Properties of Semiconductor Nanostructures using the SPHInX library” is hosted at WIAS via Project IN-7

Bottom right: Simulation work flow for Qubit devices.
Please insert any kind of pictures (photos, diagramms, simulations, graphics) related to the project in the above right field (Image with Text), by choosing the green plus image on top of the text editor. (You will be directed to the media library where you can add new files.)
(We need pictures for a lot of purposes in different contexts, like posters, scientific reports, flyers, website,…
Please upload pictures that might be just nice to look at, illustrate, explain or summarize your work.)
