D-Wave Quantum

D-Wave Quantum is one of the oldest companies in quantum computing, founded in 1999 and headquartered in Palo Alto, California, with a second base in Burnaby, British Columbia, Canada. Led by CEO Dr. Alan Baratz, it trades publicly on the New York Stock Exchange under the ticker QBTS. The company is best known for its long commitment to quantum annealing, a specialized method designed for optimization problems rather than general-purpose computation, which for most of its history made it both the leader of its niche and an outsider to the broader gate-model field.

Its flagship annealing system, Advantage2, became generally available in May 2025 with more than 4,400 qubits, accessible through the Leap real-time quantum cloud service and the open-source Ocean SDK. D-Wave positions quantum optimization and hybrid solvers, which place machine learning in the loop alongside the quantum processor, as usable for real business problems today, with named production customers including NTT DOCOMO, Ford Otosan, and Mastercard.

In March 2025, D-Wave published a beyond-classical result in the journal Science, simulating the dynamics of magnetic materials. That claim is real but contested, as research groups including teams at the Flatiron Institute reproduced parts of the computation classically using tensor-network methods, while D-Wave maintains that its largest three-dimensional simulations remain undisputed.

In January 2026, D-Wave closed its acquisition of Quantum Circuits Inc. for roughly 550 million dollars, making it the only company offering both annealing and gate-model quantum platforms. Its gate-model roadmap targets around 100 logical qubits by 2032, the same horizon it ties to its longer-term ambitions for full quantum-AI.
