RIKEN and Quantinuum Demonstrate Heterogeneous Multi-QPU Workflows on Fugaku
Researchers from Quantinuum, the University of Tsukuba, and RIKEN’s Center for Computational Science demonstrated a hybrid computing architecture that links the supercomputer Fugaku with two distinct quantum processors: Quantinuum’s Reimei trapped‑ion system and IBM’s Kobe superconducting system. Using an extended Tierkreis workflow engine, the team executed a multi‑modality quantum‑classical algorithm to compute the ground‑state energy of a 16‑site transverse‑field Ising model, achieving an error of 0.61 ± 0.36 J—substantially better than standalone VQE on Kobe (2.47 ± 0.10 J). The demonstration also validated [...]
