A dual-species atom array with alkali and alkaline-earth atoms

We present our ongoing efforts toward creating a programmable neutral atom array based on a mixture of alkali and alkaline-earth atoms. Single-species atom arrays have recently demonstrated exciting applications in quantum information, simulation, and metrology. The addition of a second atomic species, with different features, opens new possibilities for engineering many-body interactions, performing non-demolition measurements on complex entangled states, and developing new architectures for quantum information processing. Here we present progress on the realization of this new quantum platform, discussing the choice of atomic species, design considerations, and concrete near-term applications.
