D-Wave shifts to gate-model quantum hardware with dual-rail qubits

Quantum computing firm D‑Wave, long known for its annealing machines, announced a strategic pivot to gate‑model hardware. After acquiring Yale‑spun startup Quantum Circuits Inc. for $550 million, the company plans to make its first dual‑rail quantum processor generally available in 2026 and aims for a system capable of 100 logical qubits and over one million operations by 2032.

The dual‑rail architecture links two resonators per qubit, allowing photon‑loss errors to be detected directly and simplifying error‑correction. D‑Wave published a Nature paper demonstrating entanglement between two dual‑rail qubits without compromising their error‑detection advantage, marking a key validation step for the technology that could attract researchers, investors, and government buyers.
