Mitsubishi Chemical Corporation (HQ: Chiyoda-ku, Tokyo; President: Masayuki Waga; hereinafter "Mitsubishi Chemical"), IBM Japan, Ltd. (HQ: Chuo-ku, Tokyo; President: Akio Yamaguchi; hereinafter "IBM Japan"), JSR Corporation (HQ: Minato-ku, Tokyo; CEO: Eric Johnson; hereinafter "JSR"), and Keio University (Main office: Minato-ku, Tokyo; President: Akira Haseyama; hereinafter "Keio") are pleased to announce the publication of a paper in "npj Computational Materials," a specialized journal from the world-renowned publisher Nature Research. The paper presents the results of a research project on "predicting the performance of OLED light-emitting materials using a quantum computer," which has been conducted at the IBM Quantum Network Hub (located within the Keio University Quantum Computing Center).

This research project, led by Mitsubishi Chemical and IBM in collaboration with JSR and Keio, was undertaken to calculate the excited-state energy of TADF materials, a type of OLED light-emitting material. While errors specific to real quantum computers have traditionally been a challenge for such calculations, this project has successfully devised a new measurement method to reduce these errors, significantly improving calculation accuracy.

This marks the world's first successful calculation of the excited state of a practical material using a real quantum computer. In the future, as the computational power of these real devices evolves, it is expected that even more precise calculations will become possible, contributing to the design of materials with higher light-emission efficiency.

We will continue to advance research into the use of quantum computers for a wide range of materials development.
