OptQC, a University of Tokyo spinout, and NTT (the roughly $90 billion revenue Japanese telecom giant) signed a capital and business alliance agreement, with NTT planning to invest directly in OptQC, building on a November 2025 research collaboration. The joint roadmap targets a fault-tolerant, million-qubit-class optical quantum computer by fiscal year 2030, with an interim 10,000-qubit proof-of-concept system targeted for FY2028, and the companies plan proof-of-concept projects with prospective users starting FY2028. No specific investment amount was disclosed.

NTT is a large, established telecom infrastructure company making a direct capital bet on optical quantum computing, a modality distinct from the superconducting, trapped-ion, and neutral-atom approaches most of this feed's core companies use, and one that leans on NTT's existing optical communications expertise.

"NTT plans to invest" with no dollar figure disclosed is a strategic alliance announcement, not a quantifiable funding round; treat the capital commitment itself as unconfirmed until a number surfaces. The FY2030 million-qubit target is an extremely aggressive timeline for a technology that hasn't yet published component-level fidelity data comparable to trapped-ion or superconducting competitors.
