PsiQuantum and Mitsubishi UFJ Financial Group announced that they are beginning work with Mitsubishi Chemical Group on a joint project to simulate excited states of photochromic molecules which have widespread industrial and residential potential applications such as the development of smart windows, energy-efficient data storage, solar energy storage and solar cells, and other photoswitching use cases. Qlimate, a PsiQuantum-led initiative that includes MUFG as a partner, focuses on using fault-tolerant quantum computing to crack the most challenging computational problems and accelerate the development of scalable breakthroughs across climate technologies, including more energy-efficient materials. Mitsubishi UFJ Financial Group (MUFG) is committed to supporting the world?s transition to a sustainable future, and to encourage industry access to the most promising breakthrough technologies.

By pioneering PsiQuantum?s Qlimate solutions with industry leader Mitsubishi Chemical, MUFG is at the forefront of quantum computing for sustainability. This joint project will determine whether high-accuracy estimates of excited state properties are feasible on early-generation fault-tolerant quantum computers, specifically focusing on diarylethenes used for energy-efficient photoswitching applications. The project will allow Mitsubishi Chemical to gain early insights into how and when fault-tolerant quantum computing can be deployed in support of critical, scalable, sustainable materials.

Because predicting the optical properties of materials requires complex analysis of excited states, standard algorithmic techniques for simulating these molecules (such as the Density Functional Theory, or DFT) often produce qualitatively incorrect results. The project will bring together Mitsubishi Chemical?s deep experience of computational chemistry and PsiQuantum?s leading expertise in fault-tolerant quantum computing to push the boundaries of approaching the complex physics in these systems and pave the way to developing new, more powerful energy-efficient photonic materials.
