Exact QUBO optimisation, guaranteed global optimum.
A GPU-accelerated branch-and-bound engine that returns the proven minimum of any Quadratic Unconstrained Binary Optimisation problem mapped onto D-Wave's Chimera graph — up to 1024 variables, every call.
Submit through a Python SDK that mirrors the dimod interface and use the result as ground truth for molecular optimisation, logistics, portfolio selection, and network design.
Solved exactly on the 1024-qubit Chimera topology — the same footprint quantum annealers target, with provable certainty instead of probabilistic samples.
Pay-per-call cloud delivery keeps the cost of a proven optimum low enough for benchmarking heuristics in tight feedback loops.
Exact algorithms, GPU parallelism, drop-in API — a ground-truth reference for QUBOs that matter.
Patented branch-and-bound
A patented exact algorithm prunes the search tree aggressively, returning the proven global optimum rather than a best-effort approximation.
GPU-parallel search
Bound evaluation and subtree expansion run in parallel on cloud GPUs, collapsing what would be hours of CPU search into seconds.
dimod-compatible API
A Python SDK that mirrors D-Wave's dimod interface — drop the solver into existing optimisation pipelines without rewriting your problem model.
Chimera-graph alignment
Tuned for QUBOs mapped onto the 1024-qubit Chimera topology, giving the same problem footprint as a 2000Q annealer with classical certainty.
Deterministic results
The same input returns the same proven optimum every run — a ground-truth reference for benchmarking heuristics and validating quantum samplers.
Cloud-native delivery
Pay-per-call cloud service, no hardware to provision. Submit a problem, retrieve the optimum, move on with your pipeline.
