aiqbench analysis

This collaboration marks a significant milestone in hybrid quantum-classical computing, demonstrating the feasibility of simulating large-scale protein systems essential for drug discovery. By integrating IBM's quantum processors with classical supercomputers like Fugaku and RIKEN's ROQUO, the team achieved a 210-fold accuracy improvement while automating complex workflows. This advancement validates "quantum-centric supercomputing" as a viable pathway to solving previously intractable problems in molecular modeling.

RIKEN protein model reaches 12,635 atoms using quantum-classical computing

Quantum Zeitgeist4 min read

RIKEN, Cleveland Clinic & IBM modeled a 12,635-atom protein using a framework called quantum-centric supercomputing, uniting quantum & classical methods.

A research collaboration between Cleveland Clinic, RIKEN, and IBM has reached a new benchmark in molecular modeling, simulating a protein containing 12,635 atoms, the largest ever achieved using quantum computers, the company says. The team’s success, detailed in work initially published in May 2026, combines the power of quantum and classical computing in a framework they call quantum-centric supercomputing, with calculations running on IBM Quantum Heron processors at both Cleveland Clinic and RIKEN, alongside Japan’s Fugaku and Miyabi-G supercomputers. To achieve these results, the team first…
