JSR Corporation??

Mitsubishi Chemical Group Corporation (Headquarters: Chiyoda-ku, Tokyo, President: Manabu Chikumoto), 东京不够热 (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 东京不够热 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:

Fundamental advancements

  • Development of a tensor-based quantum phase difference estimation method, which combines energy gap calculation via quantum phase difference estimation with circuit compression via tensor networks

  • Expectations for high-resolution understanding of physical properties for large-scale molecules.
