QUBT

Collaboration combines INmune Bio's clinical research with QCi's  Dirac-3S quantum optimization machine to identify potential new treatment indications and biomarkers for XPro Initial engagement marks QCi's first commercial customer in pharmaceutical and biotechnology markets, expanding the application of quantum computing to drug development BOCA RATON, Fla. and HOBOKEN, N.J.

Quantinuum, backed by Honeywell's continued majority-voting stake, is still working through post-IPO price discovery following its June Nasdaq debut. IBM's quantum bet is funded by its much larger, profitable core business, giving it a longer runway than smaller pure-play competitors.

Scales quantum optimization to up to nearly 10,000 variables, a 10x increase over QCi's current 1,000-variable system, while delivering faster performance, production-ready reliability and scalable manufacturing First customer shipment of Dirac-3S upgrade expected in Q4 2026 HOBOKEN, N.J., Oct. 1, 2026 /PRNewswire/ -- 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.

QUBT pairs surging revenues, photonics expansion and a $42.5M backlog with analyst targets implying more upside than Rigetti, though execution risks remain.

NEW YORK, Sept. 28, 2026 /PRNewswire/ -- Kuehn Law, PLLC, a shareholder litigation law firm, is investigating whether certain officers and directors of Quantum Computing Inc. (NASDAQ: QUBT) breached their fiduciary duties to shareholders.

Quantum Computing and IonQ are advancing distinct quantum platforms, but profitability, execution risks and valuation shape their contrasting investment cases.

Quantum Computing's Fab 2 adds semiconductor, nanophotonics and advanced packaging capabilities that could accelerate quantum and photonics commercialization.

QUBT is advancing quantum computing with its EQC approach, Dirac-3 platform and a new three-year HBKU agreement.

First-time live demonstration combines quantum encryption and authentication on a single platform, alongside quantum key distribution and advanced instrumentation for secure optical communications HOBOKEN, N.J., Sept. 18, 2026 /PRNewswire/ -- Quantum Computing Inc. ("QCi" or the "Company") (Nasdaq: QUBT), a vertically integrated quantum company pioneering photonics and semiconductor manufacturing, today announced it will showcase, for the first time, an integrated quantum security platform that brings encryption and authentication together in a single solution, at the ECOC Exhibition 2026, September 21–23 at FYCMA in Málaga, Spain.

When I first covered Quantum Computing in early 2025, I struggled to figure out what this pre-commercial outfit really was. Quantum? Quantum adjacent? Now, I know. Yes, it definitely is quantum. It sold its first Dirac-3 quantum offering. Its closest peer is D-Wave's annealing approach. But Dirac-3 works with light and works at room temperature. QUBT is more than just quantum. It's evolving into a serious photonics company. Its TFLN chips offer an optics-based alternative to silicon. An acquisition adds a second fab facility.
