Contact Atom Computing about AC1000. Magne’s purchaser announcement schedules initial work around the turn of 2026/27; commissioning has not been verified here.
Check the current access route ↗What has been demonstrated
The June 2026 toric-code preprint reports repeated error-detection measurements with atom reloading, reaching 90 cycles in one code configuration.
What remains unresolved
Logical-memory and selected circuit demonstrations do not establish general application advantage. Magne’s announced commissioning is prospective; public self-service execution was not established by this review.
The next question to watch
Can longer logical computations and customer commissioning demonstrate reliable end-to-end operation beyond selected memory and circuit tests?
A research question, not a promised milestone.QubitWire coverage
Sources & evidence
- Quantum error correction with the toric code ↗Organization-originated source · 2 Jun 2026
Atom Computing and collaborators report up to 90 syndrome-extraction cycles with atom reloading. Comparisons of two code sizes through eight cycles show lower logical error for the larger code. This is a preprint.
- Fault-tolerant quantum computation with a neutral atom processor ↗Organization-originated source · 18 Nov 2024
Microsoft and Atom Computing report entangling 24 encoded logical qubits and a Bernstein–Vazirani experiment with up to 28 logical qubits on a 256-atom processor. The latest revision is June 2025.
- AC1000 — Atom Computing ↗Organization-originated source · Publication date not stated
Lists a 1,200-plus-physical-qubit on-premises offering, support options and OpenQASM/QIR interfaces. Product specifications and a sales contact do not establish completed general deployment.
- EIFO and Novo Nordisk Foundation acquire quantum computer for QuNorth ↗Organization-originated source · 17 Jul 2025
The Magne purchaser announcement describes Atom hardware and Microsoft software, with initial operation expected around the turn of 2026/27. EIFO also discloses investment in Atom Computing.
- Microsoft and Atom Computing offer a commercial quantum machine ↗Organization-originated source · 19 Nov 2024
Microsoft describes joint hardware experiments and integration of its qubit-virtualization software with Atom Computing hardware. This is partner evidence, not independent replication.
