IonQ shares rise after claim of quantum computing breakthrough — CNBC
Shares of quantum computing company IonQ rose after it said it had successfully demonstrated the industry’s first end-to-end quantum error decoder operating in real time. As CNBC reports, IonQ shares gained more than 11% in premarket trading, with the peak increase reaching 15%.
Decoder for error correction
The company announced the test result on September 22. According to IonQ, the development enables a single conventional computer processor to detect, correct and decode errors while the system is operating. This process takes place continuously in the background.
IonQ says the technology could ease one of the key limitations of quantum computing: previous systems were easily overloaded when correcting errors in sensitive quantum systems, causing delays.

IonQ’s head of quantum research, Nicolas Delfosse, said the company had confirmed real-time decoding across hundreds of logical qubits and millions of logical operations. According to him, operating the decoder on a single central processing unit opens a practical path to commercially scaled fault-tolerant quantum computing.
Market reaction
If the rise in quotations persists, it would be IonQ’s best trading day since August 7, when the company’s shares gained 11.8%. Shares of other quantum-sector companies also rose following the announcement: Rigetti Computing, D-Wave and Quantum Computing were up more than 4% in premarket trading.
IonQ Architecture Vice President John Gable said the empirical results support the company’s approach to fault tolerance, in which time, cost and energy consumption for solving tasks are key metrics. CNBC names Amazon Web Services, Nvidia and pharmaceutical company AstraZeneca among IonQ’s partners. IonQ recently raised its annual revenue forecast after acquiring semiconductor manufacturer SkyWater Technologies.
