Quantum approaches to chemistry and material design are expected to open horizons in almost every aspect of human life ranging from science and medicine to climate and energy. However, for most relevant problems, a full theoretical treatment of quantum dynamics is essentially impossible.
To overcome this challenge, we are establishing a fully-programmable quantum dynamics simulator which exploits Rydberg-dressed atoms to mediate interactions far beyond nearest neighbours and includes “molecular” degrees of freedom such as vibrations and correlated system-bath interactions.
