Lazy people in quantum computing use the term "fault-tolerant" to mean "I don't want to think about errors". Unfortunately for these magical thinkers, QEC will not make error rates go to zero, except in the asymptotic limit. For those of us who have to live with finite numbers like 7 or 144, logical operations on logical qubits will always have errors. If QEC is working correctly, these errors will be rarer than the physical ones, but also weirder. So you'd better understand them if you want your "fault-tolerant" quantum computer to actually work.
Fortunately my #quantinuum colleagues Matt Girling, Ben Criger, and Cristina Cirstoiu have put the effort in to start understanding a problem that many others don't even realise exists. Check it out:

Job ad 🧵 1/2
Quantinuum are looking for QEC person to join our compiler team. Ideally you know lots about QEC and a bit about compilers but the other way could work too. Full-time, permanent, based in Cambridge in England. If you are only interested in remote work, this is not for you.

Hello quantum friends. My team want to hire someone to work on adding QEC support to our quantum compilation stack. The ideal person will know about fault tolerant quantum computing and be keen to learn about how modern compiler tools work. The other way around might work too. The job is based in Cambridge, UK.
Please share!

A new quantum computer breaks Google's quantum supremacy record by 100-fold
#Quantinuum's new 56-qubit H2-1 quantum computer has surpassed Google's #Sycamore by achieving a 100-fold improvement in error correction performance.
This was achieved by using the Random Circuit Sampling algorithm.
