Dual-Species Rydberg Array paper

The BernienLab posts their latest work on the dual-species platform on the arXiv. In this work we introduce Rydberg interactions between the cesium and rubidium atoms in our arrays and explore new interaction and dynamic regimes that are unique to this approach. For instance, Förster resonances between the two types of atoms lead to resonant dipolar interactions, that can greatly enhance the interspecies interaction strength compared to the same-species strength. The Team uses the interactions to demonstrate a two-qubit gate, create entanglement and perform quantum non-demolition readout by using their previously demonstrated mid-circuit readout of an auxiliary qubit.
