Researchers across Europe will gain access to a diverse portfolio of quantum computing technologies starting August 1st, 2026, as the European High Performance Computing Joint Undertaking (EuroHPC JU) opens its quantum infrastructure to experimentation. The initiative provides access to systems including Euro-Q-Exa, Lucy, Piast-Q, and VLQ, representing superconducting qubits, photonic qubits, and trapped-ions, and aims to integrate quantum computers with existing supercomputing capabilities. This “quantum pilot access mode” is designed for users wanting to document the technical feasibility of their applications and develop essential code and algorithms, rather than simply running existing programs. The EuroHPC JU states that this step enables users to experiment with different quantum technologies to advance scientific discovery and drive innovation, with six quantum computers procured and two more co-funded through the HPCQS project, all located within Europe. EuroHPC JU Quantum Access for Testing and Development Europe’s quantum computers are now available for researchers, offering a crucial platform to test and refine emerging applications. This access is not simply about running existing programs on novel hardware, but a deliberate strategy to integrate quantum computers with Europe’s established supercomputing capabilities, enabling quantum-accelerated HPC. The EuroHPC JU’s investment focuses on a diverse portfolio of quantum technologies, including trapped ions, superconducting circuits, photonics, and more, allowing users to evaluate performance across different approaches. The first four quantum computers immediately available through this initiative are Euro-Q-Exa, Lucy, Piast-Q, and VLQ, each utilizing distinct qubit technologies; Euro-Q-Exa and VLQ are based on superconducting qubits, while Lucy employs photonic qubits and Piast-Q utilizes trapped-ions. Researchers, public institutions, and industry stakeholders can submit proposals, with the first application deadline being August 1st, 2026, followed by a monthly evaluation cycle. This access is specifically designed to facilitate the development of quantum algorithms and workflows, as well as the assessment of application feasibility. The EuroHPC
