  3. 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:

  4. #quantinuum hat on. We just announced Guppy, our #programming language for our new #quantum computer, Helios. The hardware will be publicly launched later this year, but you can get Guppy now.

    Guppy is for writing programs that run in the QPU. Unlike all other quantum computers, Helios is actually a computer. Correspondingly, Guppy offers arbitrary control and (mildly restricted) classical data structures. Guppy is strongly statically typed, and quantum data is treated linearly, so you can neither leak nor double-free qubits.

    Guppy is embedded in python, but is separately compiled, and maintains a clear distinction between compile-time (inside the python interpreter) and runtime (inside the QPU). You can use python for meta-programming (e.g. loop over all the qubits at compile time to build a static circuit, or have that same loop happen at runtime.). The two levels play nice together.

    There is also a simulator specially made to run these programs, called Selene.

    We spent a long time working on this, and I'm very proud to have it out there "for real".

  5. Kentaro and I went to visit RIKEN in Kobe today for the launch event of their new IBM system. (Quantinuum's system @ RIKEN has been operational for months 😂 ) Here's some pictures.
    1. Jay Gambetta giving a talk about all IBMs new stuff (very impressive!)
    2. Kentaro giving a talk about our H2 on H2 experiment.
    3. A couple of dorks and a supercomputer.
    4. They have a cool lecture room where the curtains open and reveal the machine hall beneath.

  6. 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.

  7. Unitary Hack!
    Quantinuum has 4 issues up in this year's Unitary Hack. If you'd like to get into some cool (actually used) open source quantum software projects you might like this. Take a look at

  8. Some pictures of the recent RIKEN workshop in Osaka. Talking about how to use quantum computers and HPC together. Pictured: Nathan Lysne, Keisuke Fujii, Simon Burton, Mike Foss-Feig and Enrico Rinaldi. I also gave a talk, as did many others not pictured. #quantinuum #riken #quantumcomputing

  9. Nice paper by my colleagues. Although I'm not an author, I did contribute by saying "you guys should do this". 🙂

  10. New paper dance! This is mainly the work of Michelle Sze in our chemistry team, but I want to also big up the TKET team (Silas and Yao) for making the compiler absolutely rip on those LCU circuits.

  11. 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!

  15. A new quantum computer breaks Google's quantum supremacy record by 100-fold

    's new 56-qubit H2-1 quantum computer has surpassed Google's by achieving a 100-fold improvement in error correction performance.

    This was achieved by using the Random Circuit Sampling algorithm.

  18. The #quantinuum thing that I work on that most people know about is the TKET compiler. But pretty soon after joining CQC (one of the precursor companies of Quantinuum) I realised we needed aa "web thing" so I started to hire people to work on it.

    Well, 6 years later and here it is.

  19. Intel Enters the Quantum Computing Horse Race With 12-Qubit Chip

    #Intel has built a #quantum #processor called #Tunnel #Falls that it will offer to research labs hoping to make the revolutionary computing technology practical.

    The Tunnel Falls processor, announced Thursday, houses 12 qubits, the fundamental quantum data processing elements.

    It's a major step in the chipmaker's attempt to develop quantum computing hardware it hopes will eventually surpass rivals.

    One notable feature of quantum computing is the tremendous variety of approaches. Intel is using electrons, storing data via quantum mechanical #spin, that's analogous to the two directions a top can spin.

    #IBM and #Google are using small electrical circuits of #superconducting materials.

    #IonQ and #Quantinuum manipulate #charged #atoms stored in a #trap.

    Other approaches involve #neutral atoms and even #photons.
