Dedicated quantum circuit repository addressing three problems

1

No Standard for Sharing

When publishing complex circuits, there's no standardized way to embed implementations in papers or supplements. Readers are left with incomplete descriptions.

2

Incomplete Descriptions

Papers show high-level concepts but omit gate parameters, dependencies, and implementation details necessary for reproduction.

3

Dead Links

References break. Repositories disappear. Two years later, the code is gone and reproducibility becomes impossible.

Making quantum computing accessible

From research to education, we've got you covered with powerful tools and intuitive interfaces.

Discover & Share

Access quantum circuits from researchers worldwide. Share your work with permanent QCR identifiers for citations in papers.

Persistent Identifiers

Every circuit gets a permanent QCR ID—like arXiv for quantum algorithms. No more broken links or lost repositories.

Run Simulations

Run simulations, visualize and share results as you build and modify your circuits.

Multiple Representations

View circuits in different formats: Python code, OpenQASM assembly, LaTeX, or circuit diagrams. Choose what works best for you.

Community-Driven

Built by the quantum computing community, for the community. Open-access, non-profit, and transparent.
For Researchers

QCR

The quantum circuit repository that makes sharing and discovering algorithms effortless. Get permanent citations for your work and build on the community's collective knowledge.
