For Contributors

Have code, tools, tutorials, or papers to share?

Persistent, versioned QCR IDs. Searchable and cross-linked. Auto-generated cross-framework translations.

Persistent, versioned IDs

Every entry gets a stable, citable QCR ID. Update your upload, old versions stay accessible.

Reach the community

Searchable and cross-linked. Your entry surfaces to readers via topics, frameworks, and related work.

Cross-framework code

Upload an assembly once. QBraid auto-generates Qiskit, Cirq, Amazon Braket, and more.
