The future of quantum computing depends on error correction, but there is still much to learn and more knowledge to share.
That's why we are thrilled to welcome @lizdurst to Riverlane as our Vice President of QEC Community! 🎉
Liz is a highly regarded leader in the quantum computing industry, best known for building IBM Quantum’s Qiskit, the open-source software development kit that now dominates the quantum computing developer tools market. With over 600,000 users and adoption in 700+ universities, Qiskit has played a pivotal role in shaping the quantum workforce.
Now, as quantum computing enters the quantum error correction (QEC) era, Liz will lead the development of a QEC software development kit along with learning resources to prepare the global quantum community for working with logical qubits and error-corrected systems.
Quantum computing is evolving rapidly, and we believe there’s now a growing need to empower the next generation of learners and innovators.
💬 Liz shares: "I am passionate about empowering people worldwide to use and advance quantum computing. Having seen firsthand how thriving open-source ecosystems can drive progress, I look forward to working with Riverlane to accelerate the path to useful fault-tolerant quantum computers."

🤔What would a 'MegaQuOp' machine do?
In collab with @uni_copenhagen, led by Andreas Juul Bay-Smidt, we've developed a method for quantum simulations of model systems in materials science and chemistry, and extended the potential use cases for early generations of fault-tolerant quantum computers.

🎉 Riverlane's landmark quantum error correction (QEC) paper has been published in Nature Electronics 🎉
This publication recognizes the breakthrough made by our quantum decoder—the world's first dedicated 'QEC chip' implemented on ASIC and FPGA hardware.
By uniquely balancing speed, accuracy, and resource efficiency, it set a new standard for quantum error correction when it was first published on arXiv in September 2023.
📖 Key highlights:
• At its release, our novel Collision Clustering (CC) decoder was the most powerful in the world, and this paper was among the first to demonstrate that QEC could provide a viable route to fault-tolerant quantum computing.
• Since then, the industry has rapidly embraced QEC, with companies like Google, Quantinuum, and QuEra also making significant QEC advancements.
• The next big milestone? Using real-time QEC to achieve a 'MegaQuOp' (one million error-free quantum operations). This is where quantum computing's first practical use cases beyond the supercomputing threshold will begin to emerge.
🚀 Riverlane is leading the charge.
Our Quantum Error Correction Stack (Deltaflow ™), the first comprehensive QEC solution for all quantum computers, will help our hardware partners transform their full-stack quantum computers into 'MegaQuop Machines'.
With our second-generation QEC Stack (Deltaflow 2) launching this March, we're steadily advancing toward this critical goal.
Today's publication in Nature Electronics is a proud moment. With QEC implementation now a top priority for every quantum computer and control system maker, we look forward to driving the continued progress of our QEC roadmap through 2025 and beyond.

Now on the arXiv: a major step towards reaching one-million error-free quantum operations (aka the MegaQuOp)
Riverlane’s Abbas Bracken Ziad and Joan Camps et al present an FPGA implementation of our Local Clustering Decoder (LCD). This solution balances both the accuracy and speed required to create a real-time decoder, paving the way for the MegaQuOp.
The LCD will be integrated in the latest version of Riverlane’s QEC Stack, Deltaflow 2.

I remain available to get increasingly deranged about this over the course of an hour to an audience of your choice.

An informal, in person evening event at our Cambridge HQ for those curious to learn more about about Riverlane and quantum computing.
🥸 Have you heard the one about the quantum computer?
It’s a complete comedy of errors...
Because of quantum error correction... get it? 🤦
Luckily, the person running the Riverlane company socials will not be writing the jokes on 19th November at 5:30pm when we welcome VP quantum science @earltcampbell and quantum scientists Laura Caune and @bbarber_ for an evening where quantum computing and comedy collide – with free pizza and drinks to kick things off in our UK Cambridge office 🍕

Never miss the meeting where they pick titles, that's my advice.

You could not choose a better person than Steve for this. Also for basically anything else you need: excellent on a stage, in front of a small group, behind a camera, or offering thoughtful advice on almost any problem you can imagine.

Oh, so now you’re saying my field _isn’t_ a special case of Physics?
Make up your minds!

After several presentations ending with a teaser about "experimental results coming soon" we posted today the outcome of a collaboration between @RiverLane_io and @rigetti showing the first demonstration of a fast and scalable FPGA decoding for reals!

One step closer to defeating Erdos's aliens!
The Ramsey number R(5) is now at most 46. (So is between 43 and 46 now - the previous upper bound was 48.)
Congratulations Brendan and Vigleik!

Been working on "Magic state cultivation: growing T states as cheap as CNOT gates" all year. It's finally out: arxiv.org/abs/2409.17595
The reign of the T gate is coming to an end. It's now nearly the cost of a lattice surgery CNOT gate, and I bet there's more improvements yet.
