If you saw my talk yesterday at QEC, this paper is the one that allows us to further improve distance of the mid cycle states further!
Check out our new work on how to make the surface code on a hexagonal grid robust to dead components: www.arxiv.org/abs/2508.08116
It turns out adding weight-1 checks to LUCI gives you a lot of new freedom!

Handling fabrication defects in hex-grid surface codes
Recent work has shown that a hexagonal grid qubit layout, with only three couplers per qubit, is sufficient to implement the surface code with performance comparable to that of a traditional four-coup...

If you're an early-career faculty member (received their PhD within seven years of submission) in quantum computing, consider applying to Google's Research Scholar Program. The application process is lightweight and the grant comes in the form of an unrestricted gift.

Check out Matt's thread on implementing the novel surface code circuits from the Relaxing Hardware Requirements pallet in experiment! It's always exciting when we can find new ways to use the resources we already have.
Circuits Galore! Check out our latest work demonstrating three new circuits for implementing the surface code: arxiv.org/abs/2412.14360 They all perform well below threshold on a device optimised for the standard surface code, but they each open up wild new possibilities for devices.
