Hamamatsu, NKT, and Yaqumo have partnered to develop photonic systems for cold-atom quantum computers, enhancing global supply chains and technology.
Hamamatsu Photonics, along with its subsidiary NKT Photonics and the startup Yaqumo, has entered into a memorandum of understanding aimed at developing and commercializing photonic systems specifically for cold-atom quantum computers.
The agreement sets the stage for collaborative research and development efforts, the production of industrial optical modules, and the formation of a global supply chain for essential components.
In quantum systems utilizing neutral atoms, photonic lasers are essential for various functions, including cooling and trapping atoms, manipulating qubit states, and reading out information.
Hamamatsu will leverage its expertise in photodetectors and ultra-sensitive imaging, while NKT will focus on creating specialized laser technologies and fiber-optic solutions. Yaqumo is set to concentrate on hardware, developing a scalable architecture based on ytterbium atoms.
The memorandum was signed on June 3 at the residence of the Danish ambassador in Japan, with notable attendees including Jingo Kikukawa from Japan's Ministry of Economy, Trade and Industry and Danish ambassador Jarl Friis-Madsen.
This initiative aligns with an intergovernmental agreement between Japan and Denmark, established in 2025, aimed at fostering cooperation in quantum technologies.
The collaboration is expected to help Japan secure a reliable supply of optical components for its burgeoning quantum industry, while Denmark seeks to enhance its status as a global manufacturing hub for high-tech equipment.
In related developments, Australian scientists recently created a full-cycle photonic chip for quantum systems, and Dutch firm QuiX Quantum installed the first Feed-Forward Control Unit for managing a photonic quantum computer in June.
