- Abstract: One of the principal goals of controlling classical chaotic dynamical systems
is known as targeting, which is the very weakly perturbative process of using
the system's extreme sensitivity to initial conditions in order to arrive at a
predetermined target state. It is shown that a generalization to chaotic
quantum systems is possible in the semiclassical regime, but requires tailored
perturbations whose effects must undo the dynamical spreading of the evolving
quantum state. The procedure described here is applied to initially minimum
uncertainty wave packets in the quantum kicked rotor, a preeminent quantum
chaotic paradigm, to illustrate the method, and investigate its accuracy. The
method's error can be made to vanish as $\hbar \rightarrow 0$

This work develops a quantum control application of many-body quantum chaos for ultracold bosonic gases trapped in optical lattices.
In the technique known as targeting, instead of a hindrance to control, the instability becomes a resource.
Explicit applications to custom state preparation and stabilization of quantum many-body scars are presented in one- and two-dimensional lattices.

We introduce the notion of steady-state quantum chaos as a general phenomenon in open quantum many-body systems.
Chaos and integrability in the steady state of an open quantum system are instead uniquely determined by the spectral structure of the time evolution generator.
We study steady-state chaos in the driven-dissipative Bose-Hubbard model, a paradigmatic example of out-of-equilibrium bosonic system without particle number conservation.

Quantum algorithms for quantum dynamics simulations are traditionally based on implementing a Trotter-approximation of the time-evolution operator.
variational quantum algorithms have become an indispensable alternative, enabling small-scale simulations on present-day hardware.
We show that, despite providing a clear reduction of quantum gate cost, the variational method in its current implementation is unlikely to lead to a quantum advantage.
