QuEra Computing
Neutral-atom quantum computing built on rubidium-87 Rydberg arrays, spun out of the Lukin, Vuletic, and Greiner groups at Harvard and MIT in 2018. Operates Aquila, the 256-qubit analog processor that has been publicly available on AWS Braket since November 2022 — the first neutral-atom machine on a major cloud. Demonstrated 48 logical qubits on a reconfigurable atom array in 2024 (Bluvstein et al., Nature 626, 58). Announced a roadmap targeting 100 logical qubits by 2026 (the Gemini line); closed a USD 230M convertible-note financing in February 2025 led by Google Quantum AI and SoftBank Vision Fund 2.
