Last year, with @Microsoft, we published a breakthrough in logical computing, demonstrating logical qubits that outperformed physical qubits by a factor of 800. This work is now published in @Nature, one of the most highly regarded scientific journals. quantinuum.com/blog/a-new-br…

Today, Quantinuum officially begins trading on NASDAQ under the ticker symbol QNT.
Today’s milestone is the direct result of the dedication of our team, trust of our partners, and support of the entire quantum community.
Thanks to everyone who helped us reach this historic day.

We’ve cut the qubit tax in time for tax season!
We’ve taken a big step toward large scale fault-tolerant quantum computing, squeezing 94 error-detected & 48 error-corrected qubits out of 98 physical qubits, an encoding that turns overhead into headroom.

With 64 of our logical qubits, we were able to simulate quantum magnetism at a scale that can be exceedingly difficult for classical computers.

We’ve demonstrated an end-to-end hybrid workflow linking the Fugaku supercomputer & the Quantinuum Reimei quantum computer.
For the first time, they operate together as an integrated, end-to-end research platform running a complete scientific workflow.

Using a layered modeling approach to biochemistry, the classical supercomputer handled the large-scale environment, while the quantum device enhanced the treatment of the challenging electronic effects in the molecular “active site” - the part that most limits accuracy in biomolecular reaction simulation.

This marks a significant milestone for Quantinuum, and the ecosystem at large: a practical step from “connected hardware” to “usable hybrid compute” for real science.

We’ve found a new approach for combinatorial optimization!
In a new paper, we introduce a tensor-network–based method that combines matrix product states with iterative local search in a novel way.

Beyond practical performance, our results help clarify the limits of classical and quantum-inspired methods for combinatorial optimization, leading to insights that are crucial for understanding where genuine quantum advantage may be possible. arxiv.org/abs/2601.21629

Our algorithms team has been hard at work identifying & enhancing areas where quantum computing can truly outperform classical methods.
Here we present an improved approach to DQI, an optimization algorithm that demonstrates a meaningful quantum speedup: arxiv.org/abs/2601.15171

Optimization problems appear everywhere.
They involve finding the best possible solution among thousands— even millions—of options. A classic example comes from the U.S. Postal Service: What’s the most efficient way to deliver millions of packages across the country each day?

In our latest work, we refine the Decoded Quantum Interferometry (DQI) framework, reducing both the qubit requirements and the runtime. It’s one more step toward making an optimized quantum future a reality.
