- IonQ said it developed and tested the industry's first end-to-end real-time quantum error decoder, running on a single standard CPU and demonstrating only 0.02% 'stretch' time in simulations involving up to 408 logical qubits and over 31.5 million quantum operations.
- The decoder validates a core component of IonQ's Walking Cat architecture, proving classical hardware overhead does not need to scale exponentially with quantum system growth and providing a practical path to commercial-scale fault-tolerant quantum computing.
- IonQ shares rose more than 11% intraday, with a premarket gain of as much as 15%, the stock's best trading day since Aug. 7 when it jumped 11.8%.
- Quantum computing peers rallied on the news, with Rigetti Computing, D-Wave and Quantum Computing all up more than 4% ahead of the open.
- IonQ's partners include Amazon Web Services, Nvidia and AstraZeneca, and the company recently raised full-year revenue guidance following its acquisition of semiconductor manufacturer SkyWater Technologies.

“Successfully validating real-time decoding across hundreds of logical qubits and over millions of logical operations is an important milestone. Moreover, the fact that our decoder runs on a single CPU provides a practical path to commercial-scale fault-tolerant quantum computing”
“Empirical evidence like this supports our vision for fault tolerance where time-to-solution, cost-to-solution, and energy-to-solution are always our North Star”
