The Institute for Molecular Science has launched a Commercialization Preparatory Platform, in collaboration with 10 industry partners, to accelerate the development of “cold (neutral) atom” quantum computers.
Institute for Molecular Science (IMS), National Institutes of Natural Sciences, has established a “Commercialization Preparatory Platform (PF)” to accelerate the development of novel quantum computers, based on the achievement of a research group led by Prof. Kenji Ohmori. The launch of the PF was made possible by collaboration with 10 industry partners, including companies and financial institutions.
The 10 partners that joined the PF include (listed alphabetically): blueqat Inc., Development Bank of Japan Inc., Fujitsu Limited, Groovenauts, Inc., Hamamatsu Photonics K.K., Hitachi, Ltd., and NEC Corporation.
Commercialization and Collaboration
With the PF in place, the IMS will leverage the expertise of the participating companies and seek for advice and support on matters related to commercialization, such as the processes of establishing a start-up company, developing domestically produced quantum computers, and R&D efforts to enable practical application of quantum computers and their associated services. It plans to launch a start-up company by the end of its FY2024 and begin the development of “cold (neutral) atom” quantum computers.

Technological Breakthroughs and Global Competition
Fierce competition is underway globally for the development of quantum computers by various modalities. However, there remain a number of issues that need to be addressed in order to ensure that these computers can be used practically; these issues include the need to expand the scale of these computers and the ability to take measures against errors that may occur during computation. In recent years, the “cold (neutral) atom” modality, which uses individual atoms as qubits, has been attracting attention from industry, academia, and governments around the world as a revolutionary new method to overcome these issues. Another feature of the cold (neutral) atom modality is that it operates at room temperature and does not require any refrigerators, which are necessary for the superconducting qubit and silicon qubit modalities.
The Ohmori group at the IMS is leading the world in developing the cold (neutral) atom quantum computers. The group has a number of technological advantages and core competencies,[1] including “optical tweezers” and microscope technologies to control a large number of high-quality qubits on a flat surface, and “ultrafast two-qubit gates” that use an ultrafast laser to create a quantum entanglement between two qubits in just 6.5 nanoseconds. In particular, the two-qubit gates represent an important core technology that enables the extraordinary computational speed of quantum computers. In 2022, the ultrafast two-qubit gates developed by the Ohmori group achieved a disruptive innovation that accelerates the two-qubit gates of the conventional cold (neutral) atom method by two orders of magnitude at once.
By taking advantage of these technical advances and core competencies of the Ohmori group, the IMS will accelerate the development and commercialization of quantum computers in collaboration with its industry partners.

World’s First Demonstration of Quantum Supremacy Using Superconducting Quantum Computers in 2019[2]
Message from Professor John Martinis, University of California, Santa Barbara:
“Professor Kenji Ohmori and his team have recently made a major breakthrough to overcome the weakness of the neutral atom method by using ultrafast lasers to drastically accelerate its two-qubit gate by two orders of magnitude. Their optical tweezers and microscope technology for manipulating individual atomic qubits is also outstanding. The team is therefore an extremely promising candidate for the realization of a practical quantum computer in the near future. I would like to actively participate in and contribute to the practical application and commercialization of their quantum computer by making use of my experience.”
Message from Yuki Takemori, General Manager, Innovation Promotion Office, Business Planning & Coordination Department, Development Bank of Japan Inc. Project General Manager of PF:
“After the bursting of the bubble economy, the Japanese economy spent the ‘lost 30 years’ without a clue to its further growth. I expect that quantum computing will be a technology that will bring revolutionary evolution to mankind, similar to the Internet and artificial intelligence (AI). It will grow into an extremely important industry for Japan, acting as a catalyst for its development and advancement. The technological capabilities of Professor Kenji Ohmori and his team are a global treasure and a trump card for the revival of the Japanese economy. I expect that this project will spread its wings far and wide.”
Message from Professor Kenji Ohmori, Institute for Molecular Science:
“I would like to express my sincere gratitude for the support of such distinguished companies for the development of our cold-atom (neutral-atom) quantum computer. Although we have absolute confidence in our basic technology, the development of practical quantum computers requires the integration of a variety of ‘enabling technologies’ including conventional electronics, software, system engineering, and architecture. With the launch of this commercialization platform, we will further strengthen our development efforts and work hard to create a quantum computer that can contribute to our society as soon as possible.”
Notes:
- Core competency: a defining capability that distinguishes an enterprise from its competitors
- Quantum supremacy: a demonstration of a quantum computer’s advantage over classical computers, including supercomputers, to process calculations that would conventionally take a long time to process at unmatched speeds

Please forget about quantum supremacy. The physical nature of quantum is the spin of topological vortices. Physics should not avoid thinking about why particles can spin. The rotation of topological vortices is spin. Topological spin endows quantum, electronic, atomic, and human beings with evolution and life via self-organization.
From energy control, chip manufacturing, to communication methods, whoever masters topological intelligence can lead and dominate the future of human society.
The perpetually swirling topological vortices defy traditional physics’ expectations. According to the theory of topological vortex gravitational fields, there is a common connection in the physical world, which is the interaction and equilibrium of topological vortex gravitational fields.

Scientific research guided by correct theories can help humanity avoid detours and failures.
Good luck to the researchers.
Hang on don’t put your money in this quite yet something better is on the cusp of invention to astonish the masses for use. Although collaboration is a formatale tool.
