Progress towards an error correcting dual-species neutral atom quantum processor

POSTER

Abstract

We present an architecture and experimental progress towards a neutral-atom quantum computer that leverages a dual-species approach of rubidium and cesium qubits, allowing for nondestructive readout of both data and ancilla registers. We present our ultra-high vacuum system capable of continuous reloading via an optical elevator beam. Our custom-designed optical pathways allow for nondestructive state-selective readout and single-photon Rydberg excitation using UV light. Further, we present a full-stack control system architecture, leveraging commercial FPGA-based hardware for low-latency coherent control.
