Mitsubishi Electric Unites with Six Organizations to Revolutionize Quantum Information Processing

In a groundbreaking move, Mitsubishi Electric Corporation has signed a joint research agreement with six prominent organizations, aiming to achieve deployable and scalable quantum information processing. This collaboration, announced on February 27, 2025, brings together a powerful alliance of industry leaders, academic institutions, and startups to tackle the challenges and unlock the potential of quantum computing.

The participating organizations include Quantinuum K.K., Keio University, SoftBank Corp., Mitsui & Co., Ltd., YOKOHAMA National University, and LQUOM, Inc. Together, they aim to connect multiple quantum computers with conventional classical computers, creating a robust and efficient information processing infrastructure. This ambitious project seeks to realize virtual large-scale quantum computing, enabling the efficient and stable operation of quantum computers through the sharing and virtualization of computational capabilities.



The key technological challenges in connecting multiple quantum computers include quantum entanglement distribution, quantum memory, quantum repeating devices, high-efficiency converters, stabilization and restoration of transmission paths, and control systems. To address these challenges, the participating organizations will develop and integrate essential components, such as quantum memory to preserve quantum states, quantum repeating devices for long-distance communication, high-efficiency converters for photon transmission, sub-systems to stabilize transmission paths, and control systems to coordinate quantum information processing devices.

By leveraging their individual strengths and expertise, the organizations will demonstrate the connection of multiple quantum computers and enhance technical readiness levels. They will collaborate with local universities and startups to evaluate these connections within a practical network environment, focusing on connections between cities such as Kawasaki, Yokohama, and Kanagawa Prefecture.



The development of these critical components is vital for the realization of virtual large-scale quantum computing. Quantum memory enables the preservation of quantum states, allowing for the transmission of quantum information over longer distances and enabling more complex computations. Quantum repeating devices facilitate the exchange of quantum entanglement, maintaining entanglement over long distances and enabling communication between distant quantum computers. High-efficiency converters transform quantum states into photons for communication, enabling the transmission of quantum information over optical fibers. Sub-systems to stabilize transmission paths and restore disturbed quantum states ensure the accuracy and reliability of quantum communication. Control systems accurately coordinate these quantum information processing devices, enabling efficient and effective collaboration between connected quantum computers.

In conclusion, Mitsubishi Electric's collaboration with six organizations marks a significant step towards the advancement of quantum information processing infrastructure. By addressing the key technological challenges and developing essential components, this joint research project aims to revolutionize the field of quantum computing and pave the way for a more interconnected and powerful future. As the participating organizations work together to overcome these challenges, they bring us one step closer to the realization of virtual large-scale quantum computing and the establishment of a comprehensive quantum information infrastructure.
