Earlybird deadline for QEC is extended til April 24th, with acceptances out on Friday!

Matt McEwen@matt.mcewen.xyz

Talks for QEC26 will be announced this Friday 17th April! We’re also extending early-bird registration until April 24th at qec-conference.org/2026/registr....

The hotel block for QEC is now up on the website at qec-conference.org/2026/travel/ The bookings are somewhat limited and must be made by May 8th, which is sooner than you'd think. I recommend that if you know you'll be attending the conference, register and reserve your room ASAP!

Registration is now open for QEC26, to be held this June in sunny Santa Barbara, CA! See the registration page at qec-conference.org for a link. Also, the deadline for submissions is next Friday. Make sure to get those in and spread the word to friends and collaborators!

The call for submissions is now live on the QEC website! Deadline is March 6th, AoE. Please consider submitting and we'd appreciate it if you spread the word! :)

The Call for Submissions for QEC26 is now up: qec-conference.org/2026/call/ Follow the link to submit your paper or poster by March 6th AOE.

Last week we put up the website for QEC26, which can be found at qec-conference.org! It should have all conference information and deadline details needed, but if anything is missing please reach out to the admin email and we’ll get back to you asap.

If you or your organisation is interested in sponsoring QEC26, please reach out to me as well and we can discuss the different sponsorship levels and opportunities we’ve set up!

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!

My favorite example is one Oscar pointed out when he first mentioned this idea, where four broken couplers in a square can lead to 4 weight-1 gauges. In this case we increase our distance by 2 in one basis!

Our team made a page on our website in case you're coming to March Meeting and interested in the work we do. Come find us and say hi!

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.

🌳 Excited to introduce Willow, Google Quantum AI’s latest chip. Willow 5x’s coherence times, beats the Surface Code QEC threshold, and the time to reproduce Willow's RCS on Frontier supercomputer is estimated at 10^25 years⏳! 👇 thread #Quantum #Physics #Science blog.google/technology/r...
