【Cleveland Clinic, RIKEN and IBM Team Advance to Finals for 2026 ACM Gordon Bell Prize】

A multidisciplinary team from Cleveland Clinic, RIKEN and IBM (NYSE: IBM) has been named as a finalist for the 2026 Association for Computing Machinery (ACM) Gordon Bell Prize for simulating the largest biologically meaningful molecules ever modeled with quantum computers, reaching a scale of 12,635 atoms.
To achieve these results, the team united the strengths of quantum and classical computing methods in a framework known as quantum-centric supercomputing.

【Spin states of hemoprotein in physiological conditions probed by nitrogen K-edge X-ray absorption spectroscopy】

A joint research team, including S***a Tsuru, Postdoctoral Researcher at the Computational Molecular Science Research Team, RIKEN Center for Computational Science (R-CCS), has successfully observed the spin states of the heme in myoglobin in aqueous solution at room temperature utilizing soft X-ray absorption spectroscopy at the nitrogen K-edge of the porphyrin ring in conjunction with electronic structure calculations.

The research team managed to observe peaks associated with the C=N π* orbitals of the porphyrin ring separately from nitrogen atoms abundantly present in the polypeptide chain. The analysis showed that the spin state of heme proteins, such as myoglobin, is influenced by temperature and the polypeptide chain, indicating the significance of in situ measurements in the functional state.

【A New Mechanism Supporting Reputation-Based Cooperation - Not only whether you help, but whether you are helped -】

An international research team including Yohsuke Murase, Senior Research Scientist at the Discrete Event Simulation Research Team, RIKEN Center for Computational Science (R-CCS), has uncovered a new mechanism that may enable the evolution of reputation-based cooperation. The team combined theoretical analysis of mathematical models with large-scale simulations using RIKEN’s supercomputer Fugaku.
