Series A
Led by Nissay Capital
Tokyo-based deep-tech startup OptQC has announced a Series A funding round led by Nissay Capital. The investment will support the development of its photonic quantum computers, which operate at room temperature and pressure, a significant departure from traditional quantum systems that require extreme cooling.
Founded in September 2024, OptQC spun out of research at the University of Tokyo. The company's optical quantum computing approach aims to reduce energy consumption and control complexity compared to other quantum architectures. Potential applications include logistics optimization, materials development, and drug discovery.
OptQC has already delivered its first machine to Japan's National Institute of Advanced Industrial Science and Technology (AIST), marking an early milestone for the young company.
The funding round was led by Nissay Capital, with no other investors disclosed. The exact amount of the round was not announced.
This Series A investment will enable OptQC to continue advancing its technology and expand its operations. The company's focus on room-temperature operation could make quantum computing more accessible and practical for a wider range of industries.
As quantum computing continues to evolve, OptQC's unique approach positions it as a notable player in the field. The support from Nissay Capital underscores the potential of photonic quantum computing to address real-world challenges.
