D-Wave’s new qubit gate cuts error rates by a factor of ten
D-Wave has developed a new qubit gate that reduces error rates by a factor of ten, as reported by Quantum Zeitgeist. This improvement is part of their superconducting gate-model quantum computing program. The gate demonstrates significantly enhanced fidelity compared to previous implementations.

This could enable D-Wave to demonstrate a logical qubit with lower error rates within the next two years, provided they can integrate the gate into a multi-qubit system with adequate connectivity.
A factor-of-ten error reduction brings gate fidelities closer to the threshold required for surface code error correction. However, achieving a logical qubit demands not only low error rates but also qubit connectivity and gate performance across a larger device. D-Wave's gate-model platform is less mature than their annealing systems, but this advance narrows the gap with other superconducting efforts.
