Summary on Grant Application Form
Accurate control of complex quantum systems is of great importance for the development of

quantum technologies, as it permits to achieve many goals with high accuracy despite inherent

system imperfections. Realising this in practice, however, is a great challenge, since it requires

precise models and numerically expensive simulations.

The central goal of this project is to develop and implement control techniques that do not

require theoretical modelling, simulation or any knowledge of a systems' microscopic

decomposition. Instead, all necessary information will be obtained directly from the experiment.

We will identify control targets that characterise desired properties of quantum systems well,

and that can be estimated accurately and efficiently in an experiment. Based on the

assessment of these targets and their dependence on tunable control parameters, we will

develop control algorithms such that an optimal control protocol is found within a minimal

number of experimental measurements.

These methods will be developed in direct interplay between simulations of experiments with

many--body systems and actual experimental implementations. In simulations we will target the

creation and stabilisation of many--body localised states and time--crystalline structures, that

will give evidence that the novel control techniques can cope with state--of--the--art quantum

many--body problems. Experimentally we will consider the preparation of highly non--classical

states of a levitated nano--sphere and the formation of large crystals of Rydberg atoms. With

an experiment on an extremely massive quantum object and an experiment with many,

strongly interacting quantum systems, we will be able to experimentally achieve goals that are

clearly out of reach with existing control techniques.

Having verified the efficacy of the control techniques, we will develop a software package and

make it publicly available such that it finds broad application in the development of quantum

technologies.
