Optimal Control of Hybrid Optomechanical Systems for Generating Non-Classical States of Mechanical Motion
Ville Bergholm, Witlef Wieczorek, Thomas Schulte-Herbrueggen +1
Cavity optomechanical systems are one of the leading experimental platforms for controlling mechanical motion in the quantum regime. We exemplify that the control over cavity optom…
Arbitrary n-Qubit State Transfer Implemented by Coherent Control and Simplest Switchable Local Noise
Ville Bergholm, F. K. Wilhelm, T. Schulte-Herbrueggen
We study reachable sets of open n-qubit quantum systems, whose coherent parts are under full unitary control, by adding as a further degree of incoherent control switchable Markovi…
How to Transfer between Arbitrary -Qubit Quantum States by Coherent Control and Simplest Switchable Noise on a Single Qubit
V. Bergholm, T. Schulte-Herbrueggen
We explore reachable sets of open -qubit quantum systems, the coherent parts of which are under full unitary control and that have just one qubit whose Markovian noise amplitude…
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…
Lie-Semigroup Structures for Reachability and Control of Open Quantum Systems: Viewing Markovian Quantum Channels as Lie Semigroups and GKS-Lindblad Generators as Lie Wedge
G. Dirr, U. Helmke, I. Kurniawan +1
In view of controlling finite dimensional open quantum systems, we provide a unified Lie-semigroup framework describing the structure of completely positive trace-preserving maps.…
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…
