TECHNOLOGY & ACCESS

What it does. Where it fits.

Dynamic portfolio QUBO formulations with variational quantum optimization and classical post-processing.

Who should look closer

Researchers benchmarking constrained quantum optimization on explicit financial models.

QubitWire’s editorial assessment of practical fit.

Restricted Qiskit Functions preview

Requires an eligible IBM plan and access arranged with Global Data Quantum; inspect limits and constraint handling before experiments.

DOCUMENTED EVIDENCE

What the sources establish

Provider materials report hardware studies up to 112 qubits and compare objectives with Gurobi. The comparison does not show quantum superiority.

quantum.cloud.ibm.com ↗arXiv paper · 2412.19150 ↗

What remains unresolved

The listed Gurobi objectives are better than quantum results, and an example reports constraint violations. These studies are not evidence of superior investment returns.

The next question to watch

External reproducible studies improving feasible-solution quality and full runtime against competitive classical methods.

A research question, not a promised milestone.

Open research questions

Editorial questions for this profile. No reviewed closure decision has been recorded; unanswered questions do not lower the official score.

Open research question

External reproducible studies improving feasible-solution quality and full runtime against competitive classical methods.

What evidence would help

A source addressing this question must identify the named system, experiment or deployment, its conditions, measured outcome and remaining limitations. Does the result count sampling, mitigation and classical processing costs?

What would resolve it?

An editorial review must explain which part of this question the evidence resolves. A roadmap or an announcement alone does not close it.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.

Suggest evidence
Open research question

Which named system or service can I use under the documented access route?

What evidence would help

Check the current terms for restricted qiskit functions preview. Identify the system version, eligibility, restrictions and whether the result used hardware or simulation.

What would resolve it?

Current primary documentation must identify the offering, eligible user and access conditions. An unspecified company-level access claim is insufficient.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.

Suggest evidence
Open research question

Does the tool support your intended hardware and workflow?

What evidence would help

Provide the source location, relevant product or generation, workload, resource constraints and reported uncertainty. Keep measurements, simulations and announced targets distinct.

What would resolve it?

A source reviewer must map the evidence to this exact scope. Missing disclosure remains unknown; it is not technical failure.

No resolved, partial or disputed outcome is asserted without a reviewed transition and its evidence.
