On September 17, IONQ Inc. rose 5.25% in regular trading, trading at $39.1/share, with turnover of $147 million. The broader quantum computing sector rallied in tandem, with Rigetti Computing and D-Wave Quantum each gaining over 5%.

On the news front, IonQ announced on September 16 that a joint research project with Oak Ridge National Laboratory, Nvidia, and the University of Tennessee demonstrated that a generative AI model can directly create quantum optimization circuits. The model eliminates repetitive parameter-tuning loops, with circuit-finding time holding steady at approximately 28 seconds across all subproblem sizes tested. During testing on a 100-variable benchmark problem, answer quality roughly doubled as subproblem sizes expanded.

The research breakthrough adds to a series of positive developments for the company, including the unveiling of its sixth-generation Superion 256 quantum-computing platform with customer deliveries expected in 2027, an $8.2 million quantum-safe network agreement with Congruity360, and a raised full-year revenue outlook to $450-$460 million following its SkyWater Technology acquisition — well above the prior analyst consensus of $289.7 million.
