Briefings

The EigenOrbit study released in November 2026 introduced eigenkit, an open-source Python library designed to run quantum algorithms across 12 different execution providers including IBM Heron and IQM Emerald. The research evaluated 12 execution providers and found that no single backend performs best across all workloads. Simulator performance varies with circuit size and structure, while hardware performance depends on circuit topology matching physical connectivity. The study highlights a broader challenge for quantum software as the ecosystem grows, requiring provider-neutral approaches to evaluate workloads before deployment.

Key points

• The EigenOrbit study released in November 2026 introduced eigenkit, an open-source Python library designed to run quantum algorithms across 12 different execution providers including IBM Heron and IQM Emerald.
• The research evaluated 12 execution providers and found that no single backend performs best across all workloads, with simulator performance varying significantly based on circuit size and structure.

Context

This research addresses the growing challenge in quantum computing where developers need to evaluate a workload across different simulators and hardware platforms without rebuilding the software workflow for each provider. The study evaluates quantum workloads across 12 execution providers, spanning simulators and quantum hardware, and includes experiments on IBM Heron and IQM Emerald quantum processors.

Limitations

The evidence is limited to the EigenOrbit study published in November 2026. The research paper is preprint status (arxiv.org/abs/2611.02979) and the findings represent experimental evaluations rather than definitive conclusions. The library supports eight simulator backends and four hardware execution routes, but specific performance metrics for each workload are not provided in the evidence.
