For over 50 years, highly excited atoms, also known as Rydberg atoms, have been widely and successfully used in both fundamental quantum research, recognised by the 2012 Nobel Prize in Physics, and applied quantum technologies. One of the primary prerequisites for these breakthroughs is measuring and controlling quantum systems at the level of a single or a few particles. In addition to the experimental achievements of the last few decades in manipulating individual quantum systems such as atoms or photons, mathematical and theoretical methods adapted to realistic experimental protocols and capabilities have played a significant role in this research. In my talk, I will present the results of our successful collaborations with theorists and mathematicians, which have enabled us to control quantum states of trapped light in real time and fully reconstruct quantum states of atom-light systems using realistic, imperfect quantum measurements.
