Tweezer arrays advance quantum computing

Subjects Biomedical materials Access through your institution Buy or subscribe Among the leading quantum computing architectures, neutral-atom systems stand out for their potential to achieve fault-tolerant, large-scale operation. This approach traps and manipulates individual atoms using magneto-optical traps and optical tweezer arrays, offering reconfigurable qubit layouts and long coherence times. However, current implementations remain limited to a few hundred qubits, and preserving coherence and imaging fidelity continues to be a challenge in the quest towards a larger number of qubits.Now, writing in Nature, Hannah Manetsch and colleagues demonstrate the trapping of more than 6,100 neutral atoms across 12,000 sites in an optical tweezer array platform (pictured; scale bar, 200 μm) (Nature 647, 60–67; 2025). Crucially, beyond scaling the number of available qubits, an impressive hyperfine qubit coherence time of 12.6(1) seconds, single-atom imaging with a survival probability of 99.98952(1)% and imaging fidelity of 99.99374(8)% are reported. These capabilities are critical for scalable quantum computing and effective quantum error correction, reinforcing the promise of neutral-atom systems for building large, fault-tolerant quantum computers.
