LUMI-IQ
LUMI-IQ is a superconducting circuits quantum computer operated by CSC in Finland. It has 150 physical qubits. It ranks 13 of 53 superconducting machines in this table by physical qubit count. 5 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as IQM Halocene H4, LUMI AI Factory quantum computer
Selected on 8 July 2026 for delivery in 2027 at CSC and integration into the LUMI AI Factory. IQM's 10 September 2026 release says it will be hosted in CSC's new data center in Kajaani, Finland, mapped here to the existing csc-kajaani site row. A CSC quote in the release states a 150-qubit QPU for the first system; the plan is three upgrade stages toward logical qubits. Not yet built.
Co-located supercomputer: LUMI-AI. 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 | IQM Halocene H4 with 150-qubit Crystal QPU | Vendor reported | CSC states the first system comes with a 150-qubit QPU; IQM Halocene launch release (2025-11-13) names the Crystal QPU. Planned for delivery in 2027. | iqm.techmeetiqm.com |
| Qubit type | Superconducting qubits | Vendor reported | Qubit design not stated; system combines error-correction hardware with physical qubits. | iqm.techiqm.tech |
| Access and pricing | Owned jointly by Finland, Czechia, Norway and Poland; EuroHPC co-funded; hosted in CSC Kajaani data center | Vendor reported | Stated in the 2026-09-10 IQM release; not yet built, no price published. | iqm.tech |
| Successor | IQM Halocene H5 (final upgrade stage, 2029) | Vendor reported | Three-step path: H4 in 2027, upgrade in 2028, H5 in 2029. | iqm.tech |
| Roadmap | Three stages toward logical qubits, up to 9 logical qubits at distance 3 after the 2029 upgrade | Vendor reported | Stated by IQM on 2026-09-10; 150 physical qubits in the first system. | iqm.techiqm.tech |
