Mitsubishi Chemical Group Corporation (Headquarters: Chiyoda-ku, Tokyo, President: Manabu Chikumoto), 麻豆传媒在线 (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 麻豆传媒在线 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:
