Scalable local addressing of atomic qubits using integrated photonics

Quantum computers based on neutral-atom qubits have emerged as promising architectures for scalable quantum computing. As the number of qubits and circuit depth grow, these optically addressed systems demand scalable and precise control solutions across multiple independent degrees of freedom in the addressing field. Here, we demonstrate a local addressing system for neutral-atom quantum computers using integrated photonics. Our multi-channel photonic integrated circuit (PIC) features high-power, high-speed switching with high extinction ratios across the visible to near-infrared spectrum. We describe our atomic-photonic integration approach and discuss the scale-up of photonic control for large-scale quantum systems.
