Oct 2025As part of a New Energy and Industrial Technology Development Organization (NEDO, Japan) project aiming to accelerate the development of quantum compute technology, Hamamatsu Photonics has been selected to develop an ultra-high-speed camera, a high-resolution, high-sensitivity camera, and a high-resolution spatial light modulator (SLM). The company will perform the development work as part of the Accelerating the Development of Quantum Computers toward Industrialization initiative, which is itself part of the NEDO-run Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems.

The project includes the development of quantum computer systems using a variety of approaches by private sector businesses, the development of components, materials, and middleware in which Japanese companies have technical strength, as well as intensive support for developing human resources.

Hamamatsu will complete development for the imagers and SLM during a period running from this year to 2027. The company specified its plan to develop prototypes for all three deliverables and said that the imagers and SLM are needed to industrialize neutral-atom-based quantum computers, especially for large-scale computations and systematization.

Hamamatsu will also develop laser stabilization technology for wavelength stabilization of laser systems as part of the project, and will evaluate and rate the prototypes to apply them to the neutral atom approach and the photonic and trapped-ion approaches. For the evaluation and testing, Hamamatsu will collaborate with the National Institute of Advanced Industrial Science and Technology, RIKEN, and domestic and foreign quantum computer manufacturers, it said.

According to Hamamatsu, the total amount of subsidy for the development work is projected to be approximately ¥3 billion ($20 million).
