On June 23, 2025, the EuroHPC Joint Undertaking inaugurated PIAST-Q in Poznań, Poland, marking the first operational deployment of a EuroHPC quantum computer. The ceremony took place under the Polish Presidency of the Council of the European Union at the Poznań Supercomputing and Networking Center (PCSS).
PIAST-Q is a laser-based trapped-ion quantum computer supplied by Alpine Quantum Technologies (AQT) of Innsbruck, Austria. According to the EuroHPC JU, the system offers 20 physical qubits with high-fidelity universal quantum gates, long coherence times, and all-to-all qubit connectivity. The procurement contract was signed less than a year earlier, and delivery occurred months ahead of schedule.
PIAST-Q cost €12.28 million ($13.6 million), with 50% funded by EuroHPC JU and 50% by the Polish Ministry of Digital Affairs and Ministry of Science and Higher Education. It is the first of eight EuroHPC quantum computers being deployed across Europe, using six different quantum computing architectures.
