D-Wave Quantum announced a new gate-model roadmap designed to accelerate the development of commercial, fault-tolerant quantum computing. Targeting 100 logical qubits capable of successfully performing over one million operations by 2032, the roadmap combines D-Wave?s expertise in high-coherence dual-rail qubits and quantum error correction, with its proven ability to engineer, scale and commercialize superconducting quantum systems. D-Wave believes the future of commercial gate-model quantum computing will be defined not by raw physical qubit counts alone, but by the ability to reliably execute large-scale computations for real-world applications. While much of the industry focuses on scaling physical qubits, D-Wave is pursuing a differentiated approach centered on reducing errors at the hardware level.
Its dual-rail qubit architecture embeds error detection directly into the qubits, making errors detectable during computation at the single-qubit level. In contrast to many other gate-model hardware modalities that cannot detect qubit errors, D-Wave?s dual-rail qubits are designed to identify approximately 90% of errors as they occur to dramatically lower the number of physical qubits required to perform error correction. D-Wave has also demonstrated, with error detection, 99.9% two-qubit fidelities, meaning physical errors occur only about once in every 1,000 operations.
The roadmap outlines a progression of technical milestones designed to improve qubit fidelity, advance large-scale computations and support the development of commercially useful quantum applications. Key roadmap milestones include: Delivery of a 17-physical-qubit system that supports logical error rates 2 times lower than physical error rates in 2026; Completion of a 49-physical-qubit system that can deliver an expected 20-fold error reduction factor over the physical error rate in 2027; Completion of a 181-physical-qubit system that can deliver an expected 2,000-fold error reduction factor over the physical error rate, representing the scalable blueprint for fault-tolerant architectures in 2028; Completion of a 10-logical-qubit system that can support the first fault tolerant algorithms in 2030; Completion of a 100-logical-qubit system capable of successfully performing more than one million operations that can support initial quantum chemistry and quantum AI applications in 2032. D-Wave?s roadmap is built on superconducting technology, which can run quantum error correction cycles 100 to 1000 times faster than neutral atom or trapped ion systems. The Company views Lambda as a key metric that should be used to measure progress toward fault-tolerant quantum computing.
Lambda is a measure of how rapidly a quantum computer?s errors are reduced as more error-correction capability is added. The broader quantum computing industry has demonstrated Lambda values around 2, meaning each increment in error correction reduces errors by about half. D-Wave?s roadmap is targeting a Lambda of 10, a major leap the Company expects will reduce errors far more quickly, by a factor of 10 for each increment in error correction, making it possible to achieve fault-tolerant quantum computing with significantly fewer physical qubits.
Combined with D-Wave?s proprietary on-chip cryogenic control technology, proven superconducting systems expertise and production-ready quantum cloud infrastructure, the Company believes its dual-rail gate-model roadmap presents a fast, efficient, and achievable path to commercial gate-model quantum computing. With more than 15 years of experience designing and building superconducting quantum computing systems, D-Wave has successfully delivered six generations of annealing quantum computers, culminating in its award winning Advantage2 system. As the only provider of annealing and gate-model technologies, D-Wave is uniquely positioned to participate in the full addressable quantum computing market.
