Riken and IBM have integrated the IBM Quantum 'Heron' processor with the Fugaku supercomputer to work concurrently on a chemistry problem, demonstrating a closed-loop workflow for quantum-centric supercomputing (QCSC). This approach allows for continuous data exchange between the systems, enhancing efficiency and scalability. The integration utilizes 152,064 classic nodes of Fugaku, leveraging a method called 'Sample-based quantum diagonalization' (SQD) to optimize task distribution between quantum and classical resources.
