Physicists have simulated key processes of photosynthesis on a quantum level with high spatial and temporal resolution. In their experiment with Rydberg atoms scientists discovered new properties of energy transport. This work is an important step towards answering the question of how quantum physics can contribute to the efficiency of energy conversion in synthetic systems, for example in photovoltaics. To be able to observe the energy transport we first had to find a way to image the Rydberg atoms. At the time it was impossible to detect these atoms using a microscope.
