Mitsui, QSimulate, and Quantinuum Launch “QIDO”: A Quantum-Integrated Chemistry Platform Targeting Faster Drug and Materials Discovery

QIDO integrates high-performance quantum chemistry workflows and quantum computing to shorten ‘molecule-to-market’ timelines across the pharmaceutical, energy, and chemical sectors, and beyond

August 19, 2025 – Tokyo, Japan – Mitsui & Co., Ltd. (“Mitsui”), QSimulate, and Quantinuum today announced the launch of a new quantum-integrated chemistry platform, “QIDO (Quantum-Integrated Discovery Orchestrator).” This platform aims to reduce the time and cost of developing new drugs and materials. QIDO accelerates research and development through high-precision chemical reaction modeling and seamlessly combines the advantages of cutting-edge classical computing and quantum computing.

Built for commercial impact, QIDO streamlines complex quantum-classical hybrid workflows and helps companies make decisions earlier in the development process, contributing to a powerful competitive advantage in innovation. The platform is designed to support research across an array of chemistry-based fields, including advanced materials design, clean energy, and drug development. 

Proprietary Technology Supporting QIDO 

QIDO seamlessly integrates QSimulate's software “QSP Reaction,” which enables calculations on the scale of thousands of atoms using the highest precision classical quantum chemistry methods and techniques. QIDO also integrates with Quantinuum's “InQuanto” software, which interfaces with state-of-the-art quantum emulators and worldleading Quantinuum Systems hardware. InQuanto achieves up to 10 times higher accuracy in simulations of complex molecules and materials compared to open-source software.

  • Makoto Koshida, General Manager, Quantum Innovation Department, Mitsui
“We take a market-needs-based approach, aiming to bridge the gap between providing practical features that help customers solve today's challenges and preparing them for the coming quantum era. This approach enables customers to maximize its benefits from day one when quantum technology comes into its own.”
  • Toru Shiozaki, Ph.D., President & CEO, QSimulate
“Combining best-in-class quantum chemical simulation with deep quantum computing expertise, QIDO gives industrial chemists powerful, intuitive algorithms and tools to tackle complex chemical challenges with speed and accuracy. We are excited about the marriage between years of innovation in quantum chemistry automation and the future of quantum computation.” 
  • Dr. Rajeeb Hazra, President & CEO, Quantinuum
“Adding the benefits of chemical accuracy and computational efficiency of quantum-native simulations in applications of chemistry is a key step forward in revolutionizing the economics of discovery in several significant end markets, such as pharmaceuticals and energy. Quantinuum is proud to offer the industry's highest-performing quantum computers and widely used quantum chemistry software to enable this progress.”

QIDO Use Cases and Future Expansion 

QIDO is launched together with a high-precision chemical reaction analysis module based on the so-called active space approach. Potential use cases are as follows: 

  • Catalysts and enzyme design
Simulating complex electron behavior to inform high-efficiency catalysts and enzymes design for cleaner energy, greener manufacturing, 
and advanced biocatalysis (useful in drug discovery, food processing, biofuel, etc.).  

  • Reaction mechanism elucidation
Enabling deeper understanding of complex chemical reaction pathways, including transient intermediates and excited states, for material stability, performance, and lifetime improvements. 

  • Battery efficiency and energy storage
Enhancing battery materials and performance for safer, longer-lasting, and higher-capacity energy storage.

  • Sustainable materials and energy
Advancing energy-efficient materials, improving carbon capture and reuse, and supporting green ammonia and hydrogen production. 


QIDO will gradually add new features to accelerate innovation in high-impact use cases, such as battery innovation and drug development. Innovation in these fields through quantum technology will be realized through 'co-creation' with our customers. 

Feedback from Industry Leaders 

As QIDO's exclusive distributor in Japan and a strategic partner with an eye toward future “co-creation,” Mitsui & Co. is leading domestic sales and distribution, laying the foundation for future global expansion. Prior to the general release of QIDO in the Japanese market, Mitsui & Co. conducted beta testing with three industry-leading companies.

  • JSR Corporation
“The platform provided by QSimulate lowers the barriers to computation by simplifying input, automating error handling, and focusing output on necessary information, making it an integral tool in the daily workflows of synthetic organic chemists at JSR. With this platform now extended to support quantum chemistry calculations on quantum computers via InQuanto, it offers a path to an early quantum advantage.” – Yu-ya Ohnishi, Ph.D., Research Fellow & Deputy Director, R&D Technology & Digital Transformation Center, Materials Informatics Promotion Office

  • Panasonic Holdings Corporation
“This platform provides users with a tool to intuitively perform chemical reaction simulations through a graphical user interface. In the anticipated era of large-scale fault-tolerant quantum computing, materials simulation is regarded as a promising application domain. Integrated with quantum computing, this platform is expected to offer opportunities for early-stage validation in preparation for future breakthroughs.” – Takahiro Ohgoe, Ph.D., Senior Lead Researcher, Green Innovation Center, Green Transformation Division
  • Chugai Pharmaceutical
“This application offers an intuitive interface that combines user-friendly operability with clear, instantly interpretable result visualization—
making reaction pathway exploration easier and more efficient than ever. At present, we recognize several technical challenges in applying the system to complex molecular calculations encountered in drug discovery and pharmaceutical research. As these challenges are steadily addressed, we expect this application to play a meaningful role in accelerating and optimizing the synthesis and process development of candidate molecules with complex chemical structures—ultimately contributing to innovation in drug discovery and the advancement of pharmaceutical development.” – Akihiko Arakawa, Ph.D., Data Science Group, Digital Solution Dept., Digital Transformation Unit
