IQM Radiance NOX at CINECA
IQM Radiance NOX at CINECA is a superconducting circuits quantum computer operated by CINECA in Italy. It has 54 physical qubits. It ranks 25 of 43 superconducting machines in this table by physical qubit count. 11 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as NOX, IQM Radiance 54
Inaugurated on 11 June 2026 by ICSC at the DAMA Tecnopolo in Bologna and described by IQM as being integrated into Leonardo. IQM calls it its second system in Italy; the first is not in this dataset. No fidelity figures are given.
Co-located supercomputer: Leonardo. 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 |
|---|---|---|---|---|
| Processor | 54-qubit IQM Crystal QPU (IQM Radiance 54) | Vendor reported | IQM says the system has a 54-qubit processing unit; Crystal 54 is the Radiance 54 chip family per the IQM Radiance and QPU pages. | iqm.techiqm.tech |
| Qubit type | transmon | Vendor reported | IQM states the Crystal 54 QPU uses superconducting transmon qubits; family-wide statement, not specific to the NOX unit. | iqm.tech |
| Topology | square lattice with tunable couplers | Vendor reported | IQM Radiance 54 datasheet text; family-wide statement. | iqm.tech |
| Max connectivity | 4 | Vendor reported | IQM describes the Crystal square lattice as having four nearest neighbors per qubit; family-wide statement, bulk qubits only. | iqm.tech |
| Native gates | PRX (arbitrary X and Y rotation) and CZ | Vendor reported | IQM Radiance datasheet says X/Y rotations and CZ are the calibrated native gates; family-wide statement. | iqm.tech |
| Cooling and environment | dilution refrigerator | Vendor reported | IQM technology page says its superconducting circuits are cooled with dilution refrigerators; family-wide statement. | iqm.tech |
| Power draw | 26 kW | Vendor reported | IQM Radiance 54 datasheet typical mean total electrical power; datasheet value, not a measurement at CINECA. | iqm.tech |
| Fabrication | IQM's own fab in Espoo, Finland | Vendor reported | IQM whitepaper says IQM QPUs are made in its dedicated Espoo facility; family-wide statement from the Garnet document. | arxiv.org |
| Software | IQM on-premises stack with HPC-integration SDK and pulse-level access | Vendor reported | IQM describes an HPC-integration SDK and pulse-level access for on-premises customers; family-wide statement. | iqm.techiqm.tech |
| Access and pricing | On-premises system at CINECA, integrated into the Leonardo supercomputer for hybrid HPC and quantum workflows | Vendor reported | Inaugurated by ICSC on 2026-06-11; no public price or user access terms are given (the second link reprints the same IQM release). | iqm.techthequantuminsider.com |
| Roadmap | Radiance systems can be upgraded with newer chips; IQM Halocene 150-qubit line due by end 2026 | Vendor reported | IQM Radiance page (checked 2026-10-09) lists upgradability; Halocene release dates are from the 2025-11-13 announcement. | iqm.techthequantuminsider.com |
