Mama etna has calmed down in time for our flight home to be undisturbed.
Surreal to see videos of scary fast pyroclastic flows only a few days after we had a tour up there! (Check the news if you don’t know what I am talking about)

Family holiday. At a loss to name this mythical creature, maybe it is the long forgotten mercentaur! It looks functional for neither sea nor land.

Going to economist quantum event in London. 1 day before look at website and surprised to see 1000+ expected attendees, with photos of previous events showing a high density of suits.
5 mins b4 leaving house recheck email and see “dress code: business attire”
Slight panic…

Thanks Alice & Bob for organising a wonderful week at Les Houches. In, particular Jeremie Guillluad.
It was a most lovely event, with great people and surroundings.
And a real balance between theory and experiment!
I have these mints as a souvenir, and my kids keep asking …

Casey presents a magic state distillation experiment on Gemini, the latest device from Quera.
There have been papers before that do MSD on physical qubits, but I think this is the first MSD demo on d>=3 encoded qubits.

(Yesterday) Bela Bauer of MS talking about their progress. Less hyper than the recent PR as the roadmap slide doesn’t claim that the 8 qubit device is “done”.

Ted Yoder summarised the onslaught of qLDPC logic papers (for fixed architectures) from IBM (and others).
I’ve read most/some of these papers but had a few gaps remaining in my understanding before today …
