LUMI-IQ
LUMI-IQ is a superconducting circuits quantum computer operated by CSC in Finland. It has 150 physical qubits. It ranks 11 of 43 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. 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 |
