Getting my submission together for QEC26 in beautiful Santa Barbara (I’m thankful it’s close to home)
Feb 27
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!

We did some experimental testing of magic state cultivation! arxiv.org/abs/2512.13908
A ~1e-4 end2end infidelity is tricky to measure with tomography, so we checked it vs more cultivation. The full escape stage is too wide for the chip, but we did try ending in the grafted code.

Cultivation is a clever protocol introduced last year to projectively measure a color code state along the “T” axis to improve fidelity. Does figure 1 demystify it?
See the theory paper too: arxiv.org/abs/2409.17595

We introduce a new measurement technique, kickback tomography, to quantify errors in logical magic states.
- Cultivation is 40x better than just injection
- Including color code QEC cycles reduces error 100x (they make the circuit distance-3)
Great to see QEC in action!

Surprise voiceover!

Communicating with qubits is tricky, they must stay isolated to preserve their state yet still “hear” our signals.
Our researchers are developing control systems that send commands and collect data without disturbing their fragile quantum states → goo.gle/3KCvOeN

As a personal project on my parental leave, I built an app #Cribside to help us manage our baby's sleep. It's a simple soothing timer and nap planner that we found really helpful.

Great new results studying topological order using quantum processors, @TU_Muenchen with @GoogleQuantumAI Willow, and Lukin group @Harvard — see thread by @PedramRoushan
4 Feb 2025
Two experiments on topological ordering in Kitaev model. A @TU_Muenchen team uses @GoogleQuantumAI Willow processor, explores the emergence of Floquet topological ordering. The Harvard team simulates fermions with this model.

But wait, there's more!
Check out this paper on dynamic circuit implementations of the surface code, such as compiling to iSwap gates. Congratulations @AEickbusch @mattjmcewen @AlexisMorvan1 and the whole team at @GoogleQuantumAI!

Like the surface code? Love the color code.
- Error suppression Λ3/5 = 1.56
- Logical randomized benchmarking
- Magic states
- Lattice surgery
Congratulations to @NathanLacroix, Alex Bourassa, and the whole team @GoogleQuantumAI and @GoogleDeepMind.
