IonQ Joins the “Three-Nines Club” Demonstrating 99.9% Two-Qubit Gate Fidelity on Its Next Generation Barium Development Platform
Mohamed Abdel-Kareem2025-07-04T10:57:38-07:00IonQ has achieved a significant breakthrough by surpassing 99.9% (three 9’s) two-qubit gate fidelity on its next-generation barium development platform. This represents a a 4X improvement over IonQ’s current commercially available systems. This milestone is a critical step toward the company’s technical roadmap of creating high-performance, enterprise-grade quantum systems, advancing the field of quantum computing. The fidelity was demonstrated using the same mechanisms employed in IonQ’s production quantum computers, helping the company understand and remove error mechanisms in larger systems. The better the native gate fidelity, the less error correction is needed. High qubit gate fidelity is essential for faster, more [...]
