A Dual Species Optical Tweezer Array of Na and Cs Atoms

Optical tweezer arrays of neutral atoms are one of the most promising platforms to realize quantum computers. A key component of a functional quantum computer is the implementation of quantum error correction, which involves building redundancy of quantum information into a larger set of physical qubits (data qubits) that comprise a single logical qubit. Successful detection and subsequent correction of errors involves entangling ancillary qubits with the data qubits and performing mid-circuit measurements of these ancillary qubits. A dual-species atom array naturally eliminates crosstalk when performing measurements of the ancillary qubits. Selective addressing of the ancillary qubits also allows for multi-qubit gates between nearby data qubits. We present our progress towards realizing a dual species tweezer array of Na and Cs atoms. We create arbitrary-geometry 2D arrays of both species in tandem and excite them to the Rydberg state.
