EigenOrbit’s research team introduced eigenkit, an open-source Python library for running quantum algorithms across multiple simulators and hardware providers through a shared interface. Its study compared 12 execution providers and reports that no backend consistently performs best: results vary by workload, circuit structure and, on hardware, how circuit topology fits processor connectivity.
EigenOrbit’s research team has introduced eigenkit, an open-source Python library for running quantum algorithms across different providers, and reports a comparison of 12 execution providers, including IBM Heron and IQM Emerald processors. The study finds that no single backend consistently performs best across workloads, making provider choice a practical consideration for researchers and developers comparing quantum execution environments.
The paper, titled “eigenkit: A Provider-Neutral Quantum Computing Library,” describes a shared interface intended to separate a quantum algorithm’s definition from the provider used to execute it. The library supports eight simulator backends and four hardware execution routes, a development relevant to broader efforts to build a full-stack quantum computing platform. According to the study, developers can run the same circuit across supported providers without rebuilding the surrounding workflow for each one.
The researchers report that simulator performance varies with circuit size, structure, batching and application workload, a consideration for science applications of quantum computing. A simulator that is suitable for one task may be less suitable for another. For hardware experiments involving IBM Heron and IQM Emerald, the better fit depended in part on how closely the circuit’s topology matched the processor’s physical connectivity, a practical issue for neutral-atom quantum computing as well.
EigenOrbit says eigenkit also provides backend-independent gradient computation and connects with tools including NumPy, PyTorch and scikit-learn. The project includes tools for quantum machine learning, optimization and chemistry, as well as benchmarking against classical baselines. The study’s core result is comparative rather than a claim that one provider or device leads overall.
Why Backend Choice Changes Results
The findings address a practical problem as quantum computing expands across different hardware architectures, simulators and cloud providers: a workflow developed for one environment may not be straightforward to compare with another. A common interface can reduce the software work needed to test the same algorithm in multiple settings, while making differences between providers easier to evaluate.
That comparison can matter for both simulation efficiency and hardware execution. The study suggests performance is not a fixed property of an algorithm alone; it can depend on the backend and on the relationship between a circuit and a processor’s connectivity. For teams choosing where to run a workload, this supports testing across candidates rather than assuming one provider is best for every task.
The report does not establish that portability by itself improves quantum results or makes one platform more capable. Its value is that researchers can compare environments using a more consistent workflow, then assess the results for their own circuits and objectives.

Quantum algorithms can be executed in software simulators or on physical quantum processors. Those environments differ in their underlying systems and constraints, so moving a workflow between providers can require changes to software and execution setup. EigenOrbit presents eigenkit as a way to keep the circuit definition and associated workflow more consistent while switching the execution provider.
The study evaluates that approach across 12 providers, rather than focusing on a single device. It includes simulator comparisons and hardware experiments on IBM Heron and IQM Emerald. The research paper is available on arXiv, and the library is published as an open-source project on GitHub. The supplied report describes the work as an experimental evaluation of provider-neutral software, not as a general ranking of all quantum systems.
“No single backend is consistently preferable across different workloads.”

Limits of the Reported Comparisons
The supplied report does not provide detailed benchmark tables, numerical performance measurements, or the full experimental settings for each provider. It is therefore not possible from the report alone to quantify the size of performance differences or determine how broadly the results apply beyond the workloads tested.
The study also does not identify a universally preferred backend, and its comparison of IBM Heron and IQM Emerald should not be read as a general ranking of those processor families. How the library performs with other circuits, provider configurations or later hardware versions remains unclear. Independent replication and further testing would help establish how the reported patterns hold across additional workloads.
Further Testing Across Workloads
The research paper, eigenkit documentation and source code are publicly available through arXiv, EigenOrbit’s website and GitHub. Developers can use the library to run supported workloads across providers and examine whether the reported differences apply to their own circuits.
The next useful evidence would include additional benchmark details, tests across a broader range of algorithms and hardware, and results that make provider settings and workload characteristics directly comparable. The report does not specify a future release schedule or a planned expansion of supported providers, so those developments remain unconfirmed.
Key Questions
What is eigenkit?
eigenkit is an open-source Python library from EigenOrbit for running quantum algorithms across supported simulators and hardware providers through a shared interface.
How many execution providers did the study evaluate?
The study evaluated 12 execution providers: eight simulator backends and four hardware execution routes, according to the report.
Which quantum processors were included?
The reported hardware experiments included IBM Heron and IQM Emerald processors. The report says processor suitability depended partly on how circuit topology matched physical connectivity.
Did the study identify a best quantum backend?
No. EigenOrbit reports that no single backend consistently performed best across the workloads evaluated. Simulator performance varied by task, while hardware suitability also depended on circuit and processor characteristics.
Where can readers find the study and software?
The paper is listed on arXiv, and eigenkit is available through EigenOrbit’s website and GitHub repository, as cited in the report.
