[Riverlane @RiverLane_io]

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.

@sp_monte_carlo The modern proof uses the existence of idempotent ultrafilters in the Stone-Cech compactification of N, which can be proved in one lecture using only basic topology. 2/2

[Ben Barber @bbarber_]

@sp_monte_carlo Hindman's theorem (for every finite colouring of the natural numbers there is an infinite subset S for which the sum of every non-empty finite subset of S is the same colour) was proved in a paper Hindman recommends reading only as penance. 1/2

@quantum_graeme @earltcampbell @jfitzsimons Here's one I snapped this morning.

It's getting pretty muddy and I'm trying to keep it nice for the holidays.

@sp_monte_carlo Trampling on @bbarber_’s field!

[Ben Barber @bbarber_]

@Kenton12323 Just a little something for you in case you need to work on your opener.

[Ben Barber @bbarber_]

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

[Ben Barber @bbarber_]

@earltcampbell Something something normaliser of the normaliser of the Pauli group.

[Ben Barber @bbarber_]

@mpaldridge @sp_monte_carlo I'm not SAYING it's a conspiracy, I'm just saying there's something going on.

[Earl T Campbell @earltcampbell]

An informal, in person evening event at our Cambridge HQ for those curious to learn more about about Riverlane and quantum computing.

[Ben Barber @bbarber_]

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

[Riverlane @RiverLane_io]

🥸 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 🍕
