We've been getting a lot of questions about alternate QEC codes, and are we looking into any? Yes! Here's experiments for two on Willow.

The color code: arxiv.org/abs/2412.14256

Dynamic surface codes: arxiv.org/abs/2412.14360
Scaling and logic in the color code on a superconducting quantum processor
Quantum error correction is essential for bridging the gap between the error rates of physical devices and the extremely low logical error rates required for quantum algorithms. Recent error-correctio...
