Feeling magical this holiday season? Check out our latest paper @GoogleQuantumAI, headlined by Emma Rosenfeld and @CraigGidney, experimentally testing magic state cultivation on Willow. arxiv.org/abs/2512.13908 |T⟩ so good it’s hard to measure: 0.9999(1), thread below! 🧵

What do I need to do to gain sufficient political power to stop these infernal time changes

It's possible to do a full 2-car garage gym setup and still park both cars. Here's a great example:

@abe_asfaw Let me introduce you to “Global Physics Summit”

Do you call it APS, or March Meeting, or both? I've always called it MM, but coming across multiple people who call it APS these days

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

@buffalu__ For all N, there is an N month sleep regression

bro how many sleep regressions are there? > 2 month sleep regression > 4 month sleep regression > 6 months sleep regression > 8 month sleep regression am i never gonna sleep again

Made a video tutorial of using crumble to create a quantum error correction circuit: youtu.be/SnpLSvyyEx8

An upbeat blog post for Christmas: Quantum Error Correction goes FOOM algassert.com/post/2503

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.

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!

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

Surprise voiceover!

Think you need a PhD for a job in quantum computing? Not necessarily, our quantum researchers joined from physics, engineering & even cryogenics. What unites them is curiosity and a drive for excellence. Learn more about Google Quantum AI team here → goo.gle/48tCV2A

@Liv_Lanes I wrote it on parental leave. The focus is timing a sequence of steps to try to prolong the first stretch of night sleep. I also put in a nap planner (calculating about wake windows to hit a target bedtime) which was better than sleep-deprived math. apps.apple.com/us/app/cribsid…

@KJSatz Hilarious. I have that book, might as well try! What does your app do??

My child is going through a sleep regression so tonight I’m going to try reading my thesis to put her to sleep from boredom

Behind building a quantum computer lies a world of subtle sounds. This ASMR journey invites you into the lab’s quiet rhythms, gentle hums, and intricate patterns of work, offering a glimpse into the focus and precision that drive scientific discovery.

#Cribside was even featured on my favorite parenting YouTube channel, The Doctors Bjorkman youtu.be/0SkFjOJW7Eo?si…

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. If you have friends with babies, please share! No ads, no subscriptions. apps.apple.com/us/app/cribsid…
