Controllability and Observability of Multi-Spin Systems: Constraints by Symmetry and by Relaxation
U. Sander, T. Schulte-Herbrueggen
We investigate the universality of multi-spin systems in architectures of various symmetries of coupling type and topology. Explicit reachability sets under symmetry constraints ar…

Quantum CISC Compilation by Optimal Control and Scalable Assembly of Complex Instruction Sets beyond Two-Qubit Gates
T. Schulte-Herbrueggen, A. Spoerl, S. J. Glaser
We present a quantum CISC compiler and show how to assemble complex instruction sets in a scalable way. Enlarging the toolbox of universal gates by optimised complex multi-qubit in…

Which Quantum Evolutions Can Be Reversed by Local Unitary Operations? Algebraic Classification and Gradient-Flow-Based Numerical Checks
T. Schulte-Herbrueggen, A. Spoerl
Generalising in the sense of Hahn's spin echo, we completely characterise those unitary propagators of effective multi-qubit interactions that can be inverted solely by {\em local}…
