Overview
- The company released two technical papers asserting a "four-nines" two-qubit gate fidelity that it calls a new world record, surpassing the 99.97% mark reported by Oxford Ionics in 2024.
- IonQ says the improvement reduces two‑qubit errors to roughly 1 in 10,000 operations versus about 3 in 10,000 at the prior record level.
- Management ties the milestone to its EQC approach that replaces laser control with integrated electronics on standard chips to improve manufacturability and stability.
- IonQ projects a 256‑qubit demonstration in 2026 and states an ambition to reach millions of qubits by 2030, framing the fidelity gain as key to scaling and fault tolerance.
- Shares rose in early trading following the announcement, as coverage contrasted the claim with peers’ recent results, including Rigetti’s reported 99.5% two‑qubit fidelity in July.
