Exploring the Limits of Controlled Markovian Quantum Dynamics with Thermal Resources
Frederik vom Ende, Emanuel Malvetti, Gunther Dirr +1
Our aim is twofold: First, we rigorously analyse the generators of quantum-dynamical semigroups of thermodynamic processes. We characterise a wide class of GKSL-generators for quan…
Reachable Sets from Toy Models to Controlled Markovian Quantum Systems
Gunther Dirr, Frederik vom Ende, Thomas Schulte-Herbrüggen
In the framework of bilinear control systems, we present reachable sets of coherently controllable open quantum systems with switchable coupling to a thermal bath of arbitrary temp…
Exploiting Matrix Symmetries and Physical Symmetries in Matrix Product States and Tensor Trains
T. Huckle, K. Waldherr, T. Schulte-Herbrueggen
We focus on symmetries related to matrices and vectors appearing in the simulation of quantum many-body systems. Spin Hamiltonians have special matrix-symmetry properties such as p…
Computations in Quantum Tensor Networks
T. Huckle, K. Waldherr, T. Schulte-Herbrueggen
The computation of the ground state (i.e. the eigenvector related to the smallest eigenvalue) is an important task in the simulation of quantum many-body systems. As the dimension…
The Significance of the -Numerical Range and the Local -Numerical Range in Quantum Control and Quantum Information
Thomas Schulte-Herbrueggen, Gunther Dirr, Uwe Helmke +1
This paper shows how C-numerical-range related new strucures may arise from practical problems in quantum control--and vice versa, how an understanding of these structures helps to…
Relative "-Numerical Ranges for Applications in Quantum Control and Quantum Information
G. Dirr, U. Helmke, M. Kleinsteuber +1
Motivated by applications in quantum information and quantum control, a new type of "-numerical range, the relative "-numerical range denoted , is introduced. It ar…
