Non-local structure, adjoint orbits, and efficient implementations of unitary transformations in three-qubit systems — •Robert Zeier — Department Chemie, Technische Universität München, Lichtenbergstrasse 4, 85747 Garching, Germany

We analyze the non-local structure of unitary transformations in three-qubit systems. Computing integral cohomology groups we gain insight into the algebraic structure of cosets with respect to local operations. We employ this information in our analysis of adjoint orbits. We discuss applications to efficient implementations of unitary transformations.
