Next-generation platform delivers faster performance, greater computing capability (up to 10,000 variables), production ready reliability and scalable manufacturing to accelerate the commercialization of quantum optimization
First customer shipment of Dirac-3S upgrade expected in Q4 2026
HOBOKEN, NJ – SEPTEMBER 30, 2026 – Quantum Computing Inc. (“QCi” or the “Company”) (Nasdaq: QUBT), a vertically integrated quantum systems company pioneering photonics and semiconductor manufacturing, today announced Dirac-3S, the next-generation of its Dirac-3 quantum optimization machine, marking a significant step toward commercial deployment of QCi’s quantum optimization technology.
Dirac-3S advances the platform across three areas – Speed, Scale and Solutions – with faster performance, improved solution quality, increased computing capacity and a modular architecture designed to support customers as their requirements grow. The first customer shipment of Dirac-3S is expected in November 2026.
Speed: Dirac-3S is engineered to accelerate computation and reduce time-to-solution for optimization workloads, enabling customers to evaluate more possibilities and iterate faster.
Scale: A modular architecture allows customers to increase computing capacity based on the size and complexity of their optimization problems. The compact 5U base configuration supports[YS1] smaller workloads, while Expansion Modules can add approximately 10,000 variables per module. Two modules, for example, can enable problem sizes of approximately 20,000 variables, with the architecture designed to scale toward approximately 100,000 variables as additional capacity is developed.
QCi has also advanced the platform’s hardware architecture, manufacturing processes and supply chain to support increased production volumes, consistent product quality and broader commercial deployment. Improvements include enhanced error correction, component control and operational reliability.
Solutions: Dirac-3S is designed to address optimization challenges across financial services, logistics and supply chains, manufacturing, energy, telecommunications, scientific research, and aerospace and defense.
The platform can be deployed on-premises or in the cloud and integrated into AI/ML pipelines, enabling organizations to incorporate quantum optimization into existing computational workflows.
“Dirac-3S takes[YS2] our quantum optimization platform from demonstrating what is possible to delivering a system built for practical commercial use,” said Yong Meng Sua, Chief Technology Officer of QCi. “We have increased performance and computing capacity, expanded the size and complexity of problems the system can address through a modular architecture, and advanced the hardware and manufacturing architecture needed tosupport broader deployment. This gives customers a flexible path to adopt quantum optimization and scale their computing capacity as their needs grow.”
Dirac-3S builds on QCi’s first-generation Dirac-3 quantum optimization machine, which has been used by academic researchers exploring quantum optimization algorithms and applications.
“Our experience with the first-generation Dirac-3 quantum optimization machine validated its potential as a powerful tool for solving meaningful optimization problems. QCi’s continued innovation with the Dirac-3S, including its expanded computational capabilities, enables us to pursue significantly larger and more complex optimization challenges. We look forward to exploring new research directions and accelerating the development of practical, high-impact applications,” said Professor Paul Griffin, Associate Professor, Singapore Management University.
In a newly published Technical Reference, QCi benchmarked Dirac-3S against a commercial optimization solver (can we name Hexaly in PR? - legal to advise). Across problem sizes from 2,000 to 9,980 [fully connected] continuous variables, Dirac-3S recovered the global optimum on 14 of 16 instances, compared with 5 for Hexaly. Dirac-3S's advantage was greatest on the largest, most difficult instances. The full methodology and results are available at (KAREN TO INSERT WEBSITE URL WHEN LIVE).

Forward-Looking Statements
This press release contains forward-looking statements as defined within Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements and forecasts, generally identified by terms such as “may,” “will,” “expect,” “believe,” “anticipate,” “estimate,” “enhance,” “intends,” “goal,” “objective,” “seek,” “attempt,” “aim to,” or variations of these or similar words, involve risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. Those statements include statements regarding the intent, belief, or current expectations of QCi and members of its management as well as the assumptions on which such statements are based. Any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties, including the timing of the first delivery, the ability of the Dirac-3S to solve larger and more complex problems than the first generation of Dirac-3, the functionality of the modular design, and delivering improvements in the performance, system maturity and manufacturability, and that actual results may differ materially from those contemplated by such forward-looking statements. Except as required by federal securities law, QCi undertakes no obligation to update or revise forward- looking statements to reflect changed conditions.[KJ4] [CR5]
