JIQCER-5
JIQCER-5 is a superconducting circuits quantum computer operated by Forschungszentrum Julich in Germany. It has 5 physical qubits. It ranks 51 of 53 superconducting machines in this table by physical qubit count. 4 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Julich IQM Quantum Computing ExpeRience, IQM Spark at Julich
Julich's first commercial gate-based superconducting quantum computer, announced in March 2024 for operation from July 2024 at under EUR 1 million for the basic version, and listed on the JUNIQ page as commissioned in late 2024 under the JUNIQ Upgrade. The page lists 5 qubits and 4 couplers. It is accessed through JUNIQ's peer-reviewed access.
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 Spark, 5 superconducting qubits | Vendor reported | Both Julich pages describe the 5-qubit IQM Spark. | fz-juelich.defz-juelich.de |
| Couplers | 4 | Vendor reported | The JUNIQ page lists 4 couplers. | fz-juelich.de |
| Cooling and environment | Superconducting circuits cooled to near absolute zero | Vendor reported | The 2024 Julich release does not give a temperature. | fz-juelich.de |
| Access and pricing | Peer-reviewed access through the JUNIQ infrastructure | Vendor reported | JUNIQ describes itself as offering peer-reviewed access to its machines. | fz-juelich.de |
