# Hamamatsu, NKT, and Yaqumo will work on photonics for quantum computers

Japanese holding company Hamamatsu Photonics, its subsidiary NKT Photonics, and startup Yaqumo signed a memorandum of understanding to jointly develop and commercialize photonic systems designed for cold-atom quantum computers.

According to the press release, the agreement lays the foundation for joint R&D projects, the creation of industrial optical modules, and the development of a global supply chain for key components.

In neutral-atom quantum systems, photon lasers play a critical role: they are used for cooling, trapping, manipulating qubit states, and subsequent readout of information.

Hamamatsu Photonics will provide expertise in photodetectors and ultra-sensitive imaging systems. NKT Photonics will develop specialized laser technologies and fiber-based solutions. Yaqumo will focus on hardware, developing its own scalable architecture based on ytterbium atoms.

The signing ceremony took place on June 3 at the official residence of the Danish ambassador in Japan.

Present at the event were Jingo Kikukawa, Director-General of the Innovation and Environment Bureau of Japan’s Ministry of Economy, Trade and Industry, and Jarl Friis-Madsen, the Danish ambassador to Japan.

Yaqumo noted that this initiative is part of the intergovernmental agreement between Japan and Denmark on cooperation in quantum technology, signed in 2025.

The partners expect that cooperation will enable Japan to ensure stable supplies of optical components for the national quantum industry, and Denmark to strengthen its position as a global hub for high-tech manufacturing.

Recall that in May, Australian scientists created a full-cycle photonic chip for quantum systems.

In June, Dutch company QuiX Quantum installed its first Feed-Forward Control Unit system designed for managing a photonic quantum computer.
