South Korea sets dual-track qubit targets for 2029, IonQ will supply its first Superion 256 system and silicon-vacancy memory module to South Korea, and post-quantum frameworks move from paper into national assessment tools and identity apps. See it all and more in today’s wrap up.
D-Wave Quantum Inc. has published peer-reviewed research in Nature demonstrating a high-fidelity two-qubit entangling gate for its superconducting dual-rail architecture. The gate achieves approximately 99.9% fidelity in about 500 nanoseconds while maintaining the experimentally observed dual-rail error hierarchy. Simulations suggest an error-reduction factor approaching 10 under favorable assumptions, with potential to reduce physical qubit overhead. The results reinforce D-Wave’s dual-platform roadmap targeting a 100-logical-qubit system by 2032.
