Researchers Susumu Date of the D3 Center and Hiroshi Ueda for Quantum Information and Quantum Biology have integrated a supercomputer with quantum processors, creating a new platform called SEAFOOD. The system directly connects the OCTOPUS supercomputer to superconducting quantum computers via the open-source OQTOPUS platform, enabling a single workflow for both quantum and classical computations. Scheduled to begin operation in December 2026, SEAFOOD was validated through a proof-of-concept implementation of a quantum-selected configuration interaction workflow.
SEAFOOD Platform Integrates OCTOPUS Supercomputer with Quantum Resources
The University of Osaka’s new SEAFOOD platform directly links classical and quantum computing resources, enabling integrated workflows starting in December 2026. This connection unites the OCTOPUS supercomputer, operated by the D3 Center, with superconducting quantum computers through the open-source quantum cloud platform, OQTOPUS. Researchers validated the system’s functionality by implementing a quantum-selected configuration interaction workflow, combining quantum sampling with extensive classical computation. Mindplex notes that the Osaka team has linked quantum computers and a supercomputer for the first time in Japan, highlighting the national significance of the achievement.
The Quantum Insider reported “SEAFOOD Puts OCTOPUS and Quantum Computers on the Same Menu”. Hiroshi Ueda’s research focuses on quantum-classical hybrid computation, developing theoretical and numerical approaches for quantum many-body systems and algorithms inspired by tensor network structures.
