This article spotlights how neutral‑atom platforms have vaulted from a niche concept into one of the few architectures now delivering both sizable qubit arrays and high‑fidelity two‑qubit gates, putting them on a competitive footing with superconducting and trapped‑ion systems. By reviewing recent algorithm demonstrations and the first logical qubits built for error correction, it shows that neutral atoms are moving beyond proof‑of‑principle toward scalable fault‑tolerant processors—a key milestone for any quantum hardware roadmap. Readers should note that while coherence times and parallel addressing have improved dramatically, challenges remain in integrating fast control electronics and reducing crosstalk as the arrays scale to thousands of atoms.

Summary
Neutral atom qubits are one of the leading approaches for implementation of a large scale quantum computer. The original proposals for neutral atom qubits were formulated more than 25 years ago, with first demonstrations of a universal gate set following 10 years later. In the last few years the performance and scale of neutral atom qubit arrays has developed at a rapid pace leading to demonstrations of quantum algorithms, and logical qubits for fault tolerant error correction. This contribution reviews the physics of the neutral atom approach, surveys current capabilities, and provides an outlook for future progress.
