D-Wave publishes two-qubit gate result in Nature with ~99.9% fidelity as first-half bookings surge 1,120%

D-Wave Quantum published a peer-reviewed paper in Nature on August 5 demonstrating a two-qubit entangling gate built on its dual-rail superconducting architecture. What the Nature paper demonstratesD-Wave Quantum published peer-reviewed research in Nature demonstrating a fast, high-fidelity two-qubit entangling gate for superconducting dual-rail cavity qubits. The paper details a new two-qubit entangling gate, a fundamental building block of quantum computation, designed to support efficient quantum error correction. On the acquisition of Quantum Circuits, closed on January 20, 2026, D-Wave described Quantum Circuits as a leading developer of error-corrected superconducting gate-model quantum computing systems. CEO Alan Baratz confirmed the 17-qubit dual-rail system remains on track for delivery by year-end.
