PIAST-Q
PIAST-Q is a trapped ions quantum computer operated by PSNC in Poland. It has 20 physical qubits. It ranks 9 of 15 trapped ion machines in this table by physical qubit count. 7 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as EuroHPC PIAST-Q
Trapped-ion computer supplied by Alpine Quantum Technologies (Innsbruck) and hosted and operated by PCSS in Poznan. It was the first EuroHPC quantum computer to be inaugurated (23 June 2025), with a stated total cost of EUR 12.28 million split equally between EuroHPC JU and two Polish ministries. It is coupled first to the ALTAIR supercomputer and later to the planned PIAST-AI system. Gate fidelities and coherence times are described only qualitatively in the sources.
Co-located supercomputer: Altair. This machine is integrated with, or hosted beside, that system.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.
| Spec | Value | Basis | Note | Source |
|---|---|---|---|---|
| Qubit type | Laser-controlled trapped ions | Independent | Both pages carry the same inauguration release text; the ion species is not stated. | eurohpc-ju.europa.euaqt.eu |
| Topology | All-to-all qubit connectivity | Independent | Same joint EuroHPC, PCSS and AQT release text on both pages (2025-06-23). | eurohpc-ju.europa.euaqt.eu |
| Cooling and environment | Room temperature, no special cooling or water needed | Independent | The release says PIAST-Q operates at room temperature and fits two 19-inch racks. | eurohpc-ju.europa.euaqt.eu |
| Power draw | 2 kW | Independent | The release says consumption is below two kilowatts, so 2 is an upper bound. | eurohpc-ju.europa.euaqt.eu |
| Fabrication | Supplied by AQT, Innsbruck, Austria | Independent | Hosted and operated by PCSS in Poznan. | eurohpc-ju.europa.euaqt.eu |
| Access and pricing | EuroHPC resource for European academic, industry and public-sector users | Independent | At inauguration on 2025-06-23 EuroHPC expected compute resources for end users by the end of 2025; no price published. | eurohpc-ju.europa.eu |
| Roadmap | Coupled first to the ALTAIR supercomputer, later to PIAST-AI | Independent | Stated at the 2025-06-23 inauguration. | eurohpc-ju.europa.euaqt.eu |
