A dual-element atom array processor

Reconfigurable arrays of neutral atoms are an exciting new platform to study quantum many-body phenomena and quantum information protocols. Their excellent coherence combined with programmable Rydberg interactions have led to intriguing observations such as quantum phase transitions, the discovery of quantum many-body scars, and the recent realization of a topological spin liquid phase.

Here, we introduce a dual-element atom array that includes both individual cesium and rubidium atoms [1]. We demonstrate that we can control both species with negligible crosstalk which enables us to operate the atom array in a continuous mode. Furthermore, we will discuss how such a dual-element architecture could enable new avenues in quantum information processing including the possibility to perform quantum non-demolition readout, the preparation of large, entangled states and the study of open systems with engineered dissipation.
