Description
We present the design and construction of a dual-element neutral-atom platform combining Rb-87 and Yb-171 for scalable quantum information processing and distribution. Encoding data and ancilla qubits in distinct atomic species suppresses optical crosstalk, enables faster two-qubit gates, and yields functionally specialized qubits within a single array. The apparatus pairs a compact dual-element source that continuously reloads a tweezer array via a conveyor-belt lattice, with a cavity array microscope reaching cooperativity of C > 1. Coupling Rydberg-interacting atoms to this cavity provides a versatile atom–photon interface for fast, non-destructive cavity-enhanced readout, mid-circuit measurement, and entanglement distribution for distributed computing and networking. The rich Yb-171 level structure supplies ground-state, metastable, and optical qubits, while rubidium offers Raman-addressed encodings. Together these ingredients target high-fidelity universal gates and efficient light–matter interfaces in a continuously operated dual-species Rydberg array.
