Pasqal JADE
Pasqal JADE is a neutral atoms quantum computer operated by Forschungszentrum Julich in Germany. It has 100 physical qubits. It ranks 7 of 10 neutral atom machines in this table by physical qubit count. 9 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Julich neutral Atom DEvice
JADE is the 100-qubit Pasqal neutral-atom quantum simulator delivered to the Julich Supercomputing Centre in late 2024 under the EuroHPC HPCQS project. It was installed in 2024 and, per JSC's JUNIQ page, moved into the JSC machine hall in 2026. The 2024 coverage said it would be coupled to JURECA-DC and be available around June 2025; no source fetched confirms that coupling is in production use. No fidelity figures are published in the pages consulted.
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 | Pasqal Fresnel system, Orion Beta generation, 100+ qubits | Independent | Julich describes JADE as a Fresnel system of Pasqal with more than 100 rubidium atom qubits; Pasqal docs list JADE as Orion Beta with 100 qubits. | fz-juelich.dedocs.pasqal.com |
| Qubit type | Rubidium atoms trapped in optical tweezers | Independent | Julich describes a configurable array of single neutral rubidium atoms; Pasqal docs describe rubidium atoms in optical tweezers. | fz-juelich.dedocs.pasqal.com |
| Topology | 1D and 2D atom registers | Independent | Julich lists 1D and 2D atom geometry; Pasqal docs list 1D and 2D register geometries. | fz-juelich.dedocs.pasqal.com |
| Native gates | Analog quantum simulator mode driven by laser pulse sequences | Independent | Julich classes JADE as an analog quantum computer of the quantum simulator type; Pasqal docs list analog mode. | fz-juelich.dedocs.pasqal.com |
| Cooling and environment | Room temperature, no cryogenics, low power | Independent | CEA press release (2025-11-13) says the Jade and Ruby systems run at room temperature with low energy use; Pasqal says zero cryogenics. | cea.frpasqal.com |
| Fabrication | Built by Pasqal (France), delivered and assembled on site at Forschungszentrum Julich | Independent | CEA says the QPUs were made by Pasqal and delivered and assembled at the CEA and FZJ centers; Julich says JADE was installed in late 2024. | cea.frfz-juelich.de |
| Software | Pulser, Eviden Qaptiva, Slurm, ParTec ParaStation Modulo | Independent | HPCQS software stack described by CEA for both Jade and Ruby. | cea.fr |
| Access and pricing | On-premises at Julich Supercomputing Centre as part of JUNIQ, with peer-reviewed access for European researchers | Independent | JUNIQ describes peer-reviewed access to its machines; its access page did not yet list a JADE route when fetched in October 2026. No price published. | fz-juelich.defz-juelich.de |
| Roadmap | Julich says its quantum computer fleet will be enhanced, expanded and fully integrated into the HPC ecosystem | Independent | Host statement from the JUNIQ page (last modified August 2026); no JADE-specific upgrade is announced. | fz-juelich.de |
