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.

Quantum Computing's surging revenues, $42.5M backlog and $1.3B cash cushion offer upside, but soaring expenses and losses keep profitability under pressure.

Partnership supports ongoing quantum research reflective of specific focus area at the University, executive education, industry applications, and workforce development in Qatar HOBOKEN, N.J., Sept. 14, 2026 /PRNewswire/ -- Quantum Computing Inc. ("QCi" or the "Company") (Nasdaq: QUBT), a vertically integrated quantum company pioneering photonics and semiconductor manufacturing, today announced it has signed a three-year Framework Agreement with Hamad Bin Khalifa University, Qatar (HBKU) to collaborate in quantum computing, quantum sensing, and quantum communications.

Shares in the five most prominent quantum computing companies are rising today despite a larger market pullback. The stock price jump in the companies controlling the nascent technology comes after three of the companies secured hundreds of millions in funding from the U.S. government.

Quantum Computing's Q2 revenues jump to $5.6 million, but rising expenses and continued losses keep profitability a key concern despite ample liquidity.
