IonQ said it validated what it describes as the quantum industry’s first end-to-end, real-time quantum error-correction decoder running on a single standard commercially available CPU, while NVIDIA selected IonQ’s Superion 256 as the first quantum processing unit for installation at its Accelerated Quantum Research Center, or NVAQC. The decoder’s dual architecture handled simulated circuits involving up to 408 logical qubits and more than 31.5 million quantum operations, adding as little as 0.02% stretch time under standard noise. The simulated test did not demonstrate hardware operating at that logical-qubit scale. Superion 256 will connect to an NVIDIA GB200 NVL72 through NVQLink, with workloads managed by CUDA-Q; customer deliveries and the NVAQC installation are scheduled for 2027. IonQ shares traded near $43, up about 6%, after reaching an intraday high of $45.93 from Tuesday’s $40.74 close. IonQ also disclosed a September 21 agreement with South Korea’s SDT for a Superion 256 system and quantum memory module.
