Overview

• The array uses optical tweezers to trap 6,100 ultracold cesium atoms, surpassing Atom Computing’s 1,180‑qubit mark.
• Qubits maintained superposition for about 13 seconds with 99.98% single‑qubit manipulation fidelity.
• Researchers shuttled atoms hundreds of micrometers across the grid while preserving superposition, a key capability for routing and error control.
• The device has not executed full computations or large‑scale entanglement, with entangling operations identified as the immediate goal.
• The Nature paper from Manuel Endres’s Caltech lab lists graduate students Hannah Manetsch, Gyohei Nomura, and Elie Bataille as lead authors.
