Quantum Computing: Continuing To Evolve And Transition From The Lab To Commerce

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.
