The QIR Alliance is a joint effort to develop a forward-looking quantum intermediate representation with the goal to enable full interoperability within the quantum ecosystem and reduce development effort from all parties.
We strive to develop a holistic solution that permits to take full advantage of unique and distinct capabilities in the landscape of heterogenous quantum processors. We are thrilled to be collaborating closely with the quantum community to design and implement the necessary compiler technology to accelerate advances in quantum programming language design and execution systems.
News and Events
Information about ongoing workstreams under the QIR Alliance and their organization, purpose, and meeting cadence can be found here. We refer to the corresponding workstream definition for more information about how to get involved. Alternatively, please reach out to email@example.com.
The following workstreams have been approved by the steering committee and are currently actively worked on:
- Specification of a Base Profile that defines the minimal requirements to
define and execute quantum programs
[workstream definition, GitHub issue]
If you would like to suggest a new workstream, please take a look at the workstream creation template, and reach out to firstname.lastname@example.org with your suggestion. Currently, creation of the following workstreams are being discussed:
- Update the QIR specification to clarify mechanisms for entry point handling,
including command line input as well as runtime initialization and
[GitHub issue ]
Steering members include Microsoft, Oak Ridge National Laboratory, Quantinuum, Quantum Circuits Inc., and Rigetti Computing (in alphabetical order). For more information about the project organization, we refer to this document.
The steering committee meets once a month. The meetings are not open to the public at this time, but minutes are published here. The steering committee may invite domain experts and repository maintainers to join the discussions. Please reach out to email@example.com if you would like to propose a topic for consideration and/or would like to volunteer your time and expertise.
Whether you are curious about our work or already deeply engaged, the following existing repositories may be interesting to you:
- qir-spec: QIR specification defining how to represent quantum programs within the LLVM IR
- pyqir [examples]: Python bindings for emitting, loading, and executing QIR.
- qcor [examples, docs]: C++ compiler for heterogeneous quantum-classical computing using QIR, including the XACC runtime
- qat [docs]: QIR compiler tools and optimization passes for targeting QIR to different hardware backends
We refer to the guidelines in the respective repository for contributions to existing repositories. Please also take a look at community forums to learn more about QIR related projects and discussions.
We welcome new repositories under the QIR Alliance from both members and non-members of the organization. If you feel your repository would fit in well under this org, please reach out to firstname.lastname@example.org. The steering committee will will approve and initiate the creation of new repositories, and facilitate the migration of existing ones.
We largely leave it up to the repository maintainers to define the rules and guidelines for their repositories, including legal matters such as a Contributor License Agreement (CLA). The only requirements for code repositories under the QIR Alliance are the following:
- At least two maintainers need to be designated for the repository, and a way to contact the maintainers should be shared with the steering committee.
- The repository is either actively maintained by the maintainers or the repository is archived.
- The Code of Conduct aligns in spirit with the Code of Conduct of the broader org.
- The project should be related in content to the goals and scope of the QIR Alliance as outlined above.
- All code should be licensed under MIT license, and contributors to the repository must accept a CLA defined by the maintainers.
The QIR Alliance will reach out to the maintainers if a repository no longer satisfies these criteria to reach an agreement and resolve the situation. If the maintainers cannot be reached or are unable to take action, the QIR Alliance reserves the right to archive the repository.
