JUPSI-2
JUPSI-2 is a quantum annealing quantum computer operated by Forschungszentrum Julich in Germany. It has 4,400 physical qubits. It ranks 1 of 6 annealing machines in this table by physical qubit count. 2 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Julich second D-Wave Advantage2, JUNIQ production annealer
The JUNIQ systems page (last modified 9 September 2026) says a second Advantage2 system, JUPSI-2, was installed in 2026 to ensure production-grade access, alongside JUPSI-1. The page lists more than 4,400 qubits for the JUPSI systems, so 4400 is a lower bound. Only the JUNIQ page was found for JUPSI-2.
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 | D-Wave Advantage2 system | Vendor reported | The JUNIQ page lists more than 4,400 qubits and more than 40,000 couplers for the JUPSI systems. | fz-juelich.de |
| Access and pricing | Second Advantage2 installed in 2026 for production-grade access through JUNIQ | Vendor reported | JUPSI-1 is kept for experiments and deep integration research with JUPITER. | fz-juelich.de |
