We present an efficient strategy for controlling a vast range of nonintegrable quantum many-body one-dimensional systems that can be merged with state-of-the-art tensor network simulation methods such as the density matrix renormalization group. To demonstrate its potential, we employ it to solve a major issue in current optical-lattice physics with ultracold atoms: we show how to reduce by about 2 orders of magnitude the time needed to bring a superfluid gas into a Mott insulator state, while…

Krylov-subspace approach for the efficient control of quantum many-body dynamics
A modified version of GRAPE is proposed that uses Krylov approximations to deal efficiently with high-dimensional state spaces and finds a constant elementary computational effort (the effort per parameter).
Quantum Many-Body Dynamics of a Disordered Electronic Spin Ensemble in Diamond
A strongly interacting driven spin system can display a variety of interesting manybody quantum phenomena due to the interplay of interaction, disorder and coherent driving. Using a dense electronic
Time evolution of open quantum many-body systems
We establish a generic method to analyze the time evolution of open quantum many-body systems. Our approach is based on a variational integration of the quantum master equation describing the
Quantum control via enhanced shortcuts to adiabaticity
Fast and robust quantum control protocols are often based on an idealised approximate description of the relevant quantum system. While this may provide a performance which is close to optimal,
Complexity of controlling quantum many-body dynamics
We demonstrate that arbitrary time evolutions of many-body quantum systems can be reversed even in cases when only part of the Hamiltonian can be controlled. The reversed dynamics obtained via

We present optimal control protocols to prepare different many-body quantum states of Rydberg atoms in optical lattices. Specifically, we show how to prepare highly ordered many-body ground states,
