NTT will invest in OptQC, and the two companies have begun joint research through fiscal year 2027 focused on qubit scaling via wavelength-division multiplexing, fault-tolerant system design, and one-million-qubit architecture. Their roadmap includes a 10,000-qubit-class system for PoC projects by 2028, a software platform for hybrid quantum-classical computing by 2029, and full-scale implementation by 2030. Target application domains include finance, manufacturing, medicine, materials science, energy optimization, and AI. ## Full article daily.dev links to this article rather than hosting it.
