EuroHPC JU Launches Procurement for MeluXina-Q Quantum Computer in Luxembourg

The EuroHPC JU has launched procurement for MeluXina-Q, a quantum computer to be hosted by LuxProvide in Luxembourg and integrated with the MeluXina supercomputer. The system will start with at least 10 semiconductor spin qubits and is planned to scale beyond 80 physical qubits. Acquisition is budgeted at up to €11.95 million ($13.6 million USD), co-financed equally by the EuroHPC JU and the Luxembourg Government. Once deployed, MeluXina-Q will support hybrid classical-quantum workflows for scientific, industrial, and public-sector users across Europe.

Quantum Elements and Planckian Partner to Develop Architecture-Specific Digital Twins for Superconducting Quantum Processors

Quantum Elements and Planckian have announced a development agreement to create architecture-specific noise models and digital twin capabilities for Planckian’s novel superconducting quantum processors. The work will characterize coherence, leakage, and operation-level errors to support evaluation of quantum error correction schemes on classical hardware. This builds on prior demonstrations of large-scale, hardware-faithful simulations, including a 97-qubit surface-code experiment. The collaboration aims to provide a realistic noise environment for designing fault-tolerant strategies ahead of physical scaling. The partnership combines Quantum Elements’ AI-powered digital twin platform with Planckian’s shared-control superconducting architecture.

Diraq Integrates NVIDIA Grace Hopper and NVQLink to Advance Utility-Scale Silicon Quantum Computing

Diraq has integrated its silicon spin qubit processors with the NVIDIA GH200 Grace Hopper Superchip through NVQLink, achieving round-trip latencies of approximately 3.3 microseconds. This hybrid quantum-classical platform supports real-time classical feedback and closed-loop control essential for scaling quantum systems. NVIDIA’s Ising models running on the GH200 now automate charge stability map analysis, reducing expert calibration from a full year of manual effort to days of model training. The architecture enables adaptive experiments and aligns Diraq’s compact semiconductor quantum processors with standard AI and HPC data center infrastructure for hybrid deployments.
