Quantum folks claim a neat flex: it’s hard for a quantum computer to tell which of two “half-the-items” states it got… but easy to swap one into the other 😼
Quantinuum (UK) and QuSoft (Netherlands) say their complement sampling algorithm beats any classical one in sample complexity, per a Physical Review Letters paper.

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:

Some of my colleagues in Tokyo talking about our collaboration with RIKEN. The video is a bit fluffy but this is pretty serious project. #quantinuum #quantum #quantumcomputing #quantinuum #riken

#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".

Dropping two new #quantinuum #qec experiment papers here. #quantum #quantumcomputing
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.

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.

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

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

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.
