Insider Brief
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 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, two-qubit entangling gate that preserves the error-correction advantages of D-Wave’s superconducting dual-rail qubit architecture. The results address one of the industry’s most consequential challenges by reducing the immense quantum and classical hardware overhead typically required to detect and correct quantum errors as systems scale.
