The researchers have successfully created a large-scale array of optical tweezers that can trap over 6,100 neutral atoms across 12,000 sites, achieving new heights in several critical performance metrics for this technology. They demonstrated: - A **coherence time** of **12.6 seconds**, a record for hyperfine qubits in an optical tweezer array. - **Trapping lifetimes** close to **23 minutes** in a room-temperature apparatus, enabling record-high - **Imaging survival** of **99.98952%** in combination with an imaging fidelity of over 99.99%. Their results, together with other recent developments, indicate that universal quantum computing with ten thousand atomic qubits could be a near-term prospect. Furthermore, their work could pave the way for quantum simulation and metrology experiments with inherent single particle readout and positioning capabilities at a similar scale.
