TechAptitude - Weekend Reading!
Quantum Qubits are highly susceptible to errors leading to decoherence. Errors can be caused by an assortment of factors such as thermal and electromagnetic fluctuations, and material defects.
So, what can be done about this fragility? We apply Error Correction - of course!
Quantum error correction (QEC) is a crucial capability in any Quantum system - learn more in this TechAptitude post!

The modality with the most qubits (superconducting) may not reach CRQC first. The modality that solves the decoder bottleneck may.
Trapped-ion systems with 100K qubits and real-time decoders could be more threatening than 1M superconducting qubits with a decoder that can't keep up. Qubit count alone misleads.

Cette percée ne se contente pas de repousser les limites théoriques de notre compréhension du réel, elle ouvre également la voie à des #ordinateurs #quantiques bien plus robustes que tout ce qui existe aujourd’hui : elle offre un moyen inédit de lutte contre le #chaos de la #décohérence #quantique , donc pour la #stabilisation de l'état des #qubits et la #correction des #erreurs #quantiques #qec : le principal #problème actuel des #ordinateurs #quantiques

#IBM affirme avoir éliminé le plus gros obstacle à l'ordinateur quantique : la #gestion des #erreurs #quantiques ( #qec #quantum #error #correction )
Et ça change absolument tout !
Une annonce ambitieuse, certes, mais qui s’appuie sur deux nouvelles études publiées début juin sur le serveur de prépublication #arXiv

Quantum Error Correction is a core linchpin for making Quantum systems stable and operational. Check out this post in the TechAptitude newsletter that outlines current quantum error correction mechanisms. https://techaptitude.substack.com/p/quantum-error-correction?r=vn8b8 #Quantum #QuamtumComputing #QEC #ErrorCorrection

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!

Найден забавный #перевод (алсо #словотворчество).
Есть такой метод ведения заметок, называется "Q/E/C": question, evidence, conclusion.
После перевода на русский: вопрос, доказательство, вывод.
И что же мы получаем? Получаем новую аббревиатуру, "В/Д/В".

Interesting roadmap from Google to scale error correction, using surface codes, to produce a large-scale fault tolerant quantum computer.
