D-Wave Publishes Research on Dual-Rail Qubit Gate for Quantum Error Correction

The Quantum InsiderAugust 5, 20264 min read

Insider Brief Press release – D-Wave Quantum Inc. (Nasdaq: QBTS), (“D-Wave” or the “Company”), the only dual-platform quantum computing company providing both annealing and gate-model systems, software, and services, today announced a major research breakthrough advancing the path to practical, fault-tolerant gate-model quantum computing. Published in the peer-reviewed scientific journal Nature, the research demonstrates a fast, high-fidelity, […]

D-Wave has published research in Nature demonstrating a two-qubit entangling gate for its dual-rail erasure qubit architecture aimed at improving quantum error correction efficiency. The company reported approximately 99.9% fidelity for two-qubit operations with gate times of about 500 nanoseconds while maintaining native hardware-level error detection. The research supports D-Wave’s gate-model roadmap focused on reducing hardware overhead requirements for fault-tolerant quantum computing systems. Press release – D-Wave Quantum Inc. (Nasdaq: QBTS), (“D-Wave” or…
