Terhal Group

The theory group led by Barbara Terhal works, in collaboration with experimental teams, on the realization of quantum error correction in various hardware platforms. Besides work on error correction, the group is interested in the theoretical description of superconducting qubit devices in general and the design of `different’ superconducting qubits. Other strands of theoretical research in which group members engage in is the use of quantum and classical algorithms for (approximate) optimization problems.
