planqc MAQCS at LRZ
planqc MAQCS at LRZ is a neutral atoms quantum computer operated by LRZ in Germany. It has 1,000 physical qubits. It ranks 3 of 13 neutral atom 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 MAQCS, Multicore Atomic Quantum Computing System
planqc leads a roughly EUR 20 million BMBF-funded project (announced 13 November 2024) to build a 1,000-qubit neutral-atom quantum computer for the Leibniz Supercomputing Centre. About 800 kg of hardware arrived at LRZ in September 2026; the system is at technology readiness level 5 with the project aiming for TRL 6 to 7 and completion targeted for end of 2027 as a quantum co-processor to LRZ's HPC systems. No operating machine at LRZ is reported yet.
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 | MAQCS, planqc multicore neutral-atom quantum computer | Vendor reported | MAQCS stands for Multicore Atomic Quantum Computing System. | thequantuminsider.com |
| Qubit type | Neutral atoms in optical lattices | Vendor reported | The article does not name the atom species. | thequantuminsider.com |
| Topology | Multicore architecture with 1,000 qubits | Vendor reported | planqc says the multicore design lets one core reset while another computes; the per-core layout is not given. | thequantuminsider.com |
| Access and pricing | Integrated into the LRZ HPC environment as a quantum co-processor | Vendor reported | LRZ says it will merge the system into its integrated HPC and quantum environment. | quantumzeitgeist.comthequantuminsider.com |
| Roadmap | Completion targeted for end of 2027, aiming for technology readiness level 6 to 7 | Vendor reported | Quantum Zeitgeist, 10 September 2026; the system is at TRL 5 as a 1,000-qubit demonstrator. | quantumzeitgeist.com |
