EuroHPC JU Launches Q-Neko Project to Strengthen EU–Japan Hybrid Quantum-HPC Collaboration

The European High Performance Computing Joint Undertaking (EuroHPC JU) has launched the Q-Neko project to strengthen collaboration with Japan in hybrid high-performance computing and quantum computing. Coordinated by CSC – IT Center for Science in Finland and funded with around €4 million from Horizon Europe, the 36-month project aims to develop software platforms, benchmarks, and standards for applications in CO₂ reduction, telecommunications, fluid dynamics, satellite image analysis, materials science, and quantum-enhanced artificial intelligence. By connecting leading EuroHPC systems with quantum hardware in Europe and Japan, including Japan’s ABCI-Q system, Q-Neko will foster expert exchanges, build a skilled workforce, and produce a technology roadmap for future EU-Japan strategic collaboration in hybrid HPC and QC technologies.

Quantum Computing Weekly Round-Up: Week Ending June 20, 2026

The quantum sector accelerated from research to real deployments and policy mandates in mid-June 2026. The UK and Japan sealed a $24 billion partnership while the US and France advanced legislation and sovereign quantum infrastructure. Hardware from IQM reached Oak Ridge National Laboratory and photonic systems arrived in Japan, with PsiQuantum starting construction on a utility-scale system in Australia. Researchers achieved passive error correction at the break-even point and companies launched scalable post-quantum security platforms. Enterprises such as Rolls-Royce and Cleveland Clinic are integrating quantum tools into industrial and medical workflows, signaling a shift to procurement.
