Synthetic quantum matter with atomic and photonic systems

In recent decades, enormous progress has been made in the control and understanding of few- and many-body quantum systems. In the future, this progress can give rise to many applications such as secure quantum communication and powerful quantum computers. In the first part of this talk, I present our theoretical and experimental studies of strongly interacting photons based on the combination of slow light polaritons and interactions between Rydberg atoms. We show that these interacting photons can be used to prepare exotic and non-classical states of light, lead to applications for quantum information processing, and give rise to strongly correlated photonic matter. In the second part of the talk, I show our progress in the control of synthetic quantum matter based on neutral atoms. We propose subwavelength-width potentials and non-destructive cooling of a quantum register, both applicable to neutral-atom quantum simulators. Finally, I show that highly-tunable interactions between Rydberg-dressed ground-state atoms can give rise to a novel phase of matter with both symmetry-broken order and topological order.
