Yaqumo, NKT Photonics, and Hamamatsu Photonics Sign MoU for Advanced Optical Systems in Quantum Computing Industrialization

For the realization and industrialization of quantum computers, it is a global challenge to not only develop processors but also to advance and secure a stable supply chain for core optical materials that underpin their performance. In neutral-atom quantum computing, high-performance optical devices are essential for trapping, cooling, manipulating, and reading out atoms, making the development of integrated modules (such as optical engines) key to industrialization.

Yaqumo is developing a Ytterbium (Yb)-based neutral-atom quantum computing architecture. NKT Photonics A/S possesses world-leading expertise in advanced laser systems and fiber laser technology, while Hamamatsu Photonics K.K. is a global leader in the development and manufacture of state-of-the-art photon detection and imaging technologies capable of single-photon level detection.

Following this, the three companies have signed a Memorandum of Understanding (MoU) regarding advanced optical systems for the industrialization of quantum computing. Through this MoU, the three companies aim to conduct joint R&D, industrialize advanced optical systems for neutral-atom quantum computing, and build a global supply chain.

Framework of Collaboration This MoU establishes a collaborative framework for the three companies to explore possibilities for joint R&D, module industrialization, and global supply chain construction in the field of core optical materials essential for quantum computing industrialization.

Leveraging their respective strengths in quantum computing hardware, laser technology, and photon detection/imaging systems, the companies will promote future collaboration ranging from the development of advanced optical devices to the industrialization of integrated systems, including optical engines.

International Cooperation This MoU is positioned as a private-sector initiative that realizes the bilateral cooperation in advanced technology fields, including quantum technology, under the Memorandum of Cooperation in the field of quantum science and technology signed between Japan and Denmark in 2025.

The signing ceremony was attended by Jingo Kikugawa, Director-General of the Innovation and Environment Bureau at the Ministry of Economy, Trade and Industry, and H.E. Peter Taksøe-Jensen (Jarl Friis-Madsen, Ambassador of Denmark to Japan), symbolizing the promotion of quantum computer industrialization based on state-level cooperation, going beyond mere private-sector collaboration.

Through this partnership, the establishment of a robust supply chain for core optical materials in the quantum computer industry is expected in Japan, while industrial growth and job creation are anticipated in Denmark by positioning the country as a core component of the global quantum industry supply chain.

Future Outlook Yaqumo, NKT Photonics, and Hamamatsu Photonics will integrate their respective expertise in quantum computing hardware, laser technology, and light detection/imaging technology to contribute to technological development for the industrialization of quantum computers and strengthen international cooperation between Japan and Denmark in the field of quantum technology.
