We are excited to share that Loom, the quantum error correction library from Entropica Labs, is now available on the updated qBraid Lab Explore page.
This integration brings hands-on surface code lattice surgery QEC tutorials directly into qBraid, allowing users to build, simulate, and decode quantum error correction experiments in a single environment.
Loom: A Python Library for Surface Code Quantum Error Correction
Loom is a Python library designed to construct and run quantum error correction (QEC) experiments, with a particular focus on surface codes and lattice surgery operations.
Entropica Labs develops software for fault-tolerant quantum computing, and Loom is one of the tools created for this purpose.The library allows researchers and developers to design and explore quantum error correction workflows programmatically, helping bridge the gap between theoretical circuits and practical experimentation.
Within these tutorials, Loom translates logical circuits into gate-level instructions that can be passed to:
- Stim, for fast stabilizer circuit simulation
- PyMatching, for minimum weight perfect matching decoding
Together, these tools form a complete QEC workflow, allowing users to move from circuit construction to simulation and decoding analysis within a single pipeline.
Launch QEC Tutorials in One Click
From the qBraid Lab Explore page, users can launch Surface Code QEC Tutorials using Loom as ready to run Jupyter notebooks.
These notebooks are:
- Interactive and notebook first
- Designed to run directly on qBraid
- Marked qBraid Ready
This means there is no need to install dependencies or configure local environments. Instead, users can immediately focus on the experiment itself: from lattice construction to simulation and decoding.

Why This Matters
Quantum error correction is essential for building scalable, fault-tolerant quantum systems.
By making Loom tutorials available directly in qBraid Lab the barrier to working with real QEC tooling is significantly lowered. Users can start experimenting with surface code QEC workflows immediately, without setting up complex simulation environments.
This collaboration between qBraid and Entropica Labs, expands the growing library of quantum applications on the Explore page and gives users immediate access to practical, research-grade workflows for quantum error.
You can now explore surface code QEC inside qBraid Lab and start experimenting right away!
