🌳 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... - ThreadSky

Hello from Brazil! I'd like to know if you believe that a quantum computer works in tandem with its counterparts from other Universes or if you don't care about it, in the so-called "shut up and calculate" approach. Thank you very much!

Also, why "Willow"?

Nicely done on all fronts :)

Yes amazing specs 🙂

Our paper published in Nature today: "Quantum error correction below the surface code threshold"

Congrats to the team on achieving this historic breakthrough👏🍾

Congrats! Curious, how did you verify the quantum computer's output is correct? (due to inability to reproduce this classically in feasible time)

juliankelly.bsky.social•156 days ago

Great question! As you point out, you can't do it directly. We run many simpler experiments that can be verified and patch them together to make a projection into the regime that is beyond classical. Our 2019 paper is a good reference https://www.nature.com/articles/s41586-019-1666-5
