D-Wave Advantage2 at Davidson
D-Wave Advantage2 at Davidson is a quantum annealing quantum computer operated by Davidson Technologies in USA. Its physical qubit count has not been published. 8 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Davidson Technologies Advantage2
An Advantage2 annealer housed at Davidson Technologies in Huntsville, Alabama, announced operational on 3 November 2025 for US government use and described as D-Wave's second annealer in the US. D-Wave says it is also reachable through Leap. The press release gives no qubit count for this specific unit, so none is recorded. Intended defence applications include radar detection and logistics, with sensitive workloads expected later.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.
| Spec | Value | Basis | Note | Source |
|---|---|---|---|---|
| Processor | Advantage2 annealing QPU (Zephyr Z12 family) | Vendor reported | Family-wide: the Davidson release does not give unit specs, so processor details come from D-Wave's Advantage2 whitepaper. | dwavequantum.comdwavequantum.com |
| Topology | Zephyr Z12 graph, 20 couplers per qubit | Vendor reported | Family-wide fact for Advantage2 systems; the Davidson press release does not restate topology for this unit. | dwavequantum.comdocs.dwavequantum.com |
| Max connectivity | 20 | Vendor reported | Family-wide nominal Zephyr degree for Advantage2; this unit's working graph is not published. | dwavequantum.comdocs.dwavequantum.com |
| Cooling and environment | Closed-loop cryogenic dilution refrigerator with RF and magnetic shielding | Vendor reported | Family-wide description of D-Wave systems in its documentation, not specific to the Davidson unit. | docs.dwavequantum.comdwavequantum.com |
| Power draw | 12.5 kW | Vendor reported | Family-wide: D-Wave says its systems use the same 12.5 kW across six generations; not measured at Davidson. | dwavequantum.com |
| Software | Ocean SDK and Leap hybrid solvers | Vendor reported | Family-wide software route for Advantage2; the Davidson release names only the Leap cloud service. | dwavequantum.comdwavequantum.com |
| Cloud platforms | D-Wave Leap | Vendor reported | D-Wave says the Davidson system is available for customer use via Leap. | dwavequantum.comdwavequantum.com |
| Access and pricing | On-premises at Davidson Technologies, Huntsville Alabama, also reachable via Leap | Vendor reported | Announced 3 November 2025 as D-Wave's second US annealer and the first in Alabama, aimed at US government applications; no price published. | dwavequantum.com |
