Mitsubishi Chemical Group Corporation (Headquarters: Chiyoda-ku, Tokyo, President: Manabu Chikumoto), ´ºÓêÖ±²¥app (Located: Minato-ku, Tokyo, President: Kohei Itoh), Softbank Corporation (Headquarters: Minato-ku, Tokyo, President: Junichi Miyakawa), and JSR Corporation (Headquarters: Minato-ku, Tokyo, President: Tetsuro Hori) have developed a method for energy gap calculation of large systems using quantum computers. This work is the result of collaborative efforts within the IBM Quantum Network Hub, a part of the ´ºÓêÖ±²¥app Quantum Computing Center. The resulting manuscript has been published in the Proceedings of the National Academy of Sciences (PNAS) and can be accessed at the following URL:
