D-Wave announces general availability of its sixth-generation 4,400-qubit Advantage2 annealing quantum computer
On 2025-05-20 D-Wave announced general availability of Advantage2, its sixth-generation annealing quantum computer, accessible to all customers via the Leap cloud service. Per D-Wave, the ~4,400-qubit system uses the Zephyr topology with 20-way connectivity and delivers a 40% increase in energy scale, a 75% reduction in noise, and roughly double the qubit coherence versus the prior Advantage generation, while drawing about 12.5 kilowatts. A separate on-premises Advantage2 is planned at Davidson Technologies for national-security research.
A commercial-grade general-availability launch of a named processor with published connectivity, noise, energy-scale, and coherence improvements is a concrete, third-party-accessible architectural advance, fitting the §8 score-7/8 band for a named processor launch with specified performance gains.
Moving Advantage2 from preview to full GA hardens D-Wave's annealing commercialization just as it recognizes its first system sale, and the energy-efficiency framing (flat 12.5kW across six generations) targets the cost-and-power narrative against gate-model competitors and classical HPC.
