Quantum computing is currently transitioning from the research stage to practical application, including the rapid acceleration of technological development for industrial use. Against this backdrop, Mitsubishi Electric has positioned quantum computing as a key priority of its overall R&D strategy by promoting research and development targeting the commercial implementation of quantum technologies. Going forward, Mitsubishi Electric aims to establish technological superiority in quantum computing and accelerate R&D to achieve early commercial adoption. At JIJ, we use mathematical optimization and quantum computing technologies to transform complex business challenges into computational forms. It is also providing a development environment that enables diverse users to solve complex, real-world business challenges through mathematical optimization.
