 ◦ Quantinuum’s Helios computer achieves a world-record 99.9995% logical fidelity—
   just five errors in a million operations—using the company’s error-correction
   architecture.
 ◦ Error rate is 10x lower than Quantinuum’s own September 2026 record and 100x 
   lower than the best published result across all other hardware modalities, which
   was reported by Google Quantum AI using a superconducting system.
 ◦ Quantinuum’s successive breakthroughs used different codes on the same hardware,
   demonstrating how its error-correction architecture and trapped-ion technology
   drive rapid gains in accuracy, with performance now in the target range for Apollo.

BROOMFIELD, Colo., Oct. 19, 2026 /PRNewswire/ — Quantinuum (NASDAQ: QNT), a leading
full-stack quantum computing company, today announced a world-record quantum error-
correction result, achieving a logical fidelity of 99.9995% on its Helios commercial
computer using the company’s error-correction architecture. This marks Quantinuum’s
second breakthrough in two months, demonstrating how its highly accurate trapped-
ion hardware and flexible architecture work together to deliver rapid improvements
in accuracy.

The achievement reinforces Quantinuum’s error-correction leadership and validates
that its accuracy performance is now within the target range for Apollo, the company’s
planned universal fault-tolerant quantum computer expected to be available by 2029.

Quantinuum’s architecture is an end-to-end framework programmable through the company’s
developer platform. It integrates tailored AI decoders, all-to-all qubit connectivity,
high-fidelity physical operations, and hardware-level error correction. This architecture
also allows the company to test, refine, and combine different error-correction 
codes and optimize between accuracy and efficiency.

In the latest study, Quantinuum used a well-known ‘color code’ within this architecture
to achieve the world-record logical fidelity result, which is equivalent to just
five errors per million operations. The error rate is 10 times lower than Quantinuum’s
own world record achieved last month and 100 times lower than the [best published result](https://www.nature.com/articles/s41586-024-08449-y)
across all other hardware modalities, which was reported by Google Quantum AI on
a superconducting system.

"With this result, we’ve proven that we have the error-correction architecture and
trapped-ion technology required to achieve universal fault-tolerance," said Dr. 
Rajeeb Hazra, CEO of Quantinuum. "We have reduced error rates tenfold in rapid succession
using a different code on the same commercial hardware, demonstrating the flexibility
of our error-correction architecture. We’ve crossed the threshold necessary for 
exponential improvements in accuracy, reinforcing our path to Apollo and how we 
can help users unlock commercial value from quantum at scale."

The study also showed that logical errors fell exponentially as Quantinuum increased
the ‘code distance,’ a technique used to understand how many physical qubits are
needed to protect quantum information as the error correction scales. Each tested
increase reduced the remaining logical errors by a record factor of 12, demonstrating
increasingly effective error suppression as the code grows—a critical capability
for scaling fault-tolerant quantum computing. Quantinuum believes this result suggests
it can deliver fault-tolerance with significantly fewer qubits than are required
for other modalities.

"This is a significant milestone that quantum computing researchers have been working
toward for many years," said Robin Blume-Kohout, Co-director of Sandia National 
Laboratories’ Quantum Performance Lab, who was not involved in the study. "The paper
demonstrates real, serious performance gains from quantum error correction—a logical
qubit nearly 100x better than its component physical qubits. A scaled-up version
of this system could reach the reliability required for useful fault-tolerant computation
at a feasible size—less than a million physical qubits—which improves the outlook
for practical quantum computing. These findings go a long way to retire one of the
field’s central technical risks."

In September 2026, Quantinuum used the same error-correction architecture with its
Helix code to demonstrate record-setting logical memory and computation. Both studies
ran on the same Helios hardware.

The two demonstrations illustrate how Quantinuum can rapidly prototype different
error-correction codes within the same architecture to optimize for relative strengths
in accuracy, efficiency, and speed. On Helios, Helix used 10 physical qubits per
logical qubit, compared with up to 37 for the color code, while the color code delivered
lower logical error rates. This provides insight into which applications pair best
with each code as systems advance toward fault-tolerance.

Quantinuum’s error-correction architecture is flexible, allowing for adaptive syndrome
extraction, which adjusts error-checking measurements during computation, and chain-
mapping, which connects codes suited to different computational tasks. Together 
with efficient code structures and real-time decoding, these techniques provide 
multiple ways to reduce errors and resource requirements.

Quantinuum is combining its hardware, error-correction architecture, and full-stack
software platform into an integrated system for fault-tolerant quantum computing.
As customers prepare for this next era of computing, Quantinuum is providing the
tools needed to develop and scale quantum applications capable of addressing challenges
across materials science, chemistry, finance, logistics, and other critical sectors.
