D-Wave says an updated version of its Stride hybrid solver found better solutions than its previous version in company benchmarks, including traveling-salesperson tests. The company also launched three Applied Quantum Optimization courses; the benchmark results are vendor-reported, and broader independent testing was not included in the supplied report.
D-Wave announced an updated version of its Stride hybrid solver, reporting that it found better optimization solutions in less time than the prior version in company benchmarks. The update covers traveling-salesperson and assembly-line balancing problems, and comes with a new three-course training path for developers using D-Wave’s Leap quantum cloud service.
D-Wave said the updated solver’s core algorithm was enhanced and that the system combines quantum and classical computing resources. In tests involving traveling-salesperson problems with up to 10,000 locations, D-Wave reported that solutions averaged within 0.02% of the best possible result after 15 seconds. At the same runtime, the company said the results were, on average, more than 200 times closer to the best possible result than those from the previous Stride version.
For traveling-salesperson problems with more than 10,000 locations, D-Wave reported solutions averaging within 3.8% of the best possible result after 120 seconds. The company said those results were, on average, more than 500 times closer to the best possible result than the previous solver’s results at the same runtime. In simple assembly-line balancing tests, D-Wave said the updated version produced better solutions in 15 seconds than its earlier version produced in 120 seconds.
The announcement also includes a three-course Applied Quantum Optimization learning path. D-Wave said the courses teach learners to identify suitable optimization use cases, create mathematical models and develop applications with Stride. Some courses include access to Leap and office hours. The company said the courses are intended for learners with varying levels of experience.
Faster Results for Scheduling Problems
Optimization problems such as route planning and assembly-line balancing involve choosing among many possible combinations under time or resource constraints. If the company’s benchmark results carry over to operational workloads, reaching higher-quality solutions sooner could help organizations test plans or revise them more quickly. That potential is relevant where decisions need to be updated as conditions change, although the announcement does not document deployments or business outcomes.
The results also matter to developers evaluating hybrid computing tools. D-Wave is positioning Stride as a way to combine quantum and classical resources for large optimization tasks, while the new courses are intended to lower the practical barrier to trying that approach. The announcement offers vendor-reported performance comparisons, not evidence that the solver will outperform alternatives on every problem or in every production setting.

Stride’s Hybrid Optimization Role
Stride is D-Wave’s hybrid solver for optimization problems and is offered through the company’s Leap quantum cloud service. A hybrid solver uses quantum and classical computing resources together; the announcement does not specify how work is divided between them for each benchmark or provide implementation-level details about the updated algorithm.
D-Wave describes itself as a dual-platform quantum computing company, offering annealing and gate-model systems as well as software and services. This announcement concerns the Stride solver and its reported optimization performance, not a change to the company’s hardware platforms. The training launch is linked to the solver update as a way to support use-case selection, modeling and application development.
“Developers need proven technology that finds better answers, faster, so they can tackle computationally complex problems at the speed their businesses demand.”
— Alex Condello, D-Wave senior vice president of algorithms, performance and tools
Benchmark Scope and Independent Tests
The figures in the announcement come from D-Wave’s benchmark testing. The supplied report does not give the benchmark datasets, hardware configuration, test repetitions, statistical variation or precise method used to calculate distance from the best possible result. It also does not identify an independent evaluator or provide comparisons with other commercial solvers.
It is not clear how the reported gains translate to customer workloads, or whether they hold across the full range of optimization problems Stride supports. D-Wave said the results show the types of improvements it expects across a wide range of problems, but that expectation is not the same as results demonstrated in every problem category. The announcement does not name customers using the updated solver or quantify financial or operational effects.
Access and Practical Evaluation
D-Wave said the enhanced Stride solver is available now through Leap, and that the three Applied Quantum Optimization courses are also available through the service. Developers interested in evaluating the update can use the cloud service and course materials to model relevant optimization tasks, subject to the access terms D-Wave provides.
Further information that would help assess the claims includes benchmark methods and datasets, independent tests, and results from customer deployments on real workloads. The announcement does not set a date for additional benchmark releases or describe a separate validation program, so those details remain pending.
Key Questions
What did D-Wave announce?
D-Wave announced an updated Stride hybrid solver and a three-course Applied Quantum Optimization learning path. Both are available through its Leap quantum cloud service, according to the company.
What performance did D-Wave report?
For traveling-salesperson problems with up to 10,000 locations, D-Wave said solutions averaged within 0.02% of the best possible result in 15 seconds. For problems above 10,000 locations, it reported an average distance of 3.8% after 120 seconds. These are company-reported benchmark figures.
Were the benchmark results independently verified?
The supplied announcement does not identify an independent evaluator. It does not provide enough detail about datasets, hardware or test procedures to assess the results independently.
What do the new courses cover?
The three courses cover identifying optimization use cases, formulating mathematical models and building applications with Stride. D-Wave says some courses include Leap access and office hours.
