Introduction

The Qiskit C API is a crucial component of the Qiskit framework, providing a low-level interface for developers to interact with the Qiskit quantum computing platform. As the Qiskit project continues to evolve, it is essential to ensure that the C API remains up-to-date and aligned with the latest developments in the project. In this article, we will explore the process of adding the VF2PostLayout functionality to the C API, enhancing the overall functionality and usability of the Qiskit C API.

Background

The VF2PostLayout is a crucial component of the Qiskit framework, responsible for post-processing the output of the VF2 algorithm. Currently, portions of the VF2PostLayout pass are written in Rust, while the majority of the logic remains in Python. As part of the ongoing effort to port the Qiskit codebase to Rust, the VF2PostLayout pass is being rewritten in Rust, with the progress tracked in Issue #12276.

Adding VF2PostLayout to the C API

Once the VF2PostLayout pass is fully rewritten in Rust, it is essential to add it as a standalone function to the C API. This will enable developers to access the VF2PostLayout functionality directly from the C API, enhancing the overall usability and flexibility of the Qiskit C API. The process of adding the VF2PostLayout function to the C API is described in Issue #14245.

Benefits of Adding VF2PostLayout to the C API

The addition of the VF2PostLayout function to the C API will bring several benefits to the Qiskit community:

  • Improved usability: By providing direct access to the VF2PostLayout functionality from the C API, developers will be able to use the VF2PostLayout pass more easily and efficiently.
  • Enhanced flexibility: The addition of the VF2PostLayout function to the C API will enable developers to use the VF2PostLayout pass in a wider range of scenarios, including custom applications and workflows.
  • Better integration: The VF2PostLayout function will be fully integrated with the C API, enabling seamless interaction between the VF2PostLayout pass and other Qiskit components.

Implementation Details

To add the VF2PostLayout function to the C API, the following steps will be taken:

  1. Rust code review: The rewritten VF2PostLayout pass in Rust will be thoroughly reviewed to ensure that it meets the required standards and quality expectations.
  2. C API integration: The VF2PostLayout function will be integrated with the C API, ensuring that it is properly documented and exposed to developers.
  3. Testing and validation: The VF2PostLayout function will be thoroughly tested and validated to ensure that it works correctly and as expected.

Conclusion

The addition of the VF2PostLayout function to the C API will be a significant enhancement to the Qiskit C API, providing developers with direct access to the VF2PostLayout pass and enabling seamless interaction between the VF2PostLayout pass and other Qiskit components. By following the implementation details outlined above, we can ensure that the VF2PostLayout function is properly integrated with the C API and meets the required standards and quality expectations.

Future Work
