Quantum science with a dual-species Rydberg array

Arrays of neutral atoms are a powerful platform for quantum information processing and quantum simulation. In this poster we will present developments from our dual-species array of rubidium and cesium atoms. With this system we recently realized crucial capabilities for neutral-atom processors, including mid-circuit measurements and real-time feed-forward, which we leveraged to mitigate correlated errors in a 2D array of up to 120 atomic qubits [1]. Here we will show experimental and theoretical progress in the implementation of dual-element Rydberg gates, the key remaining ingredient to perform non-destructive stabilizer measurements and investigate quantum error correction. We will further discuss novel opportunities offered by asymmetric intra- and inter-species interactions for multi-qubit gates, state preparation protocols, and quantum simulation.
