Atom Computing 1180-Qubit System
Atom Computing 1180-Qubit System is a neutral atoms quantum computer operated by Atom Computing in USA. It has 1,180 physical qubits. It ranks 2 of 10 neutral atom machines in this table by physical qubit count. 8 sourced specs are in the spec sheet. 2 published benchmark or milestone records are listed below, each marked by who measured it.
Also known as 1,225-site ytterbium array
Atom Computing's October 2023 next-generation platform with 1,225 trap sites populated with 1,180 qubits, announced as the first gate-based system to pass 1,000 qubits. The company stated qubits can hold quantum information for about 40 seconds and support mid-circuit measurement. The announcement said systems would be available in 2024. Gate fidelities, the machine's location and any later logical-qubit runs on this exact unit are not stated in the page 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 | 1,225-site ytterbium atom array; commercial AC1000 platform lists 1,200+ qubits | Vendor reported | The 2023 release does not use the AC1000 name; the link to the 1,200+ qubit AC1000 generation is inferred from matching scale. | thequantuminsider.comatom-computing.com |
| Qubit type | 171Yb nuclear-spin qubit | Vendor reported | AC1000 specification table lists Ytterbium-171 and nuclear-spin qubits; this is a platform-level fact, the 2023 release does not name the isotope. | atom-computing.comatom-computing.com |
| Topology | All-to-all connectivity | Vendor reported | Atom Computing says parallel arbitrary atom movement enables all-to-all connectivity; stated for the AC1000 platform. | atom-computing.comatom-computing.com |
| Cooling and environment | Atoms laser-cooled and optically trapped, operating at room temperature | Vendor reported | Atom says it cools, traps and controls qubits with lasers; its CEO says its atoms offer high fidelity at room temperature (January 2026). | atom-computing.comatom-computing.com |
| Software | OpenQASM and QIR APIs, 20-qubit emulator | Vendor reported | AC1000 specification table; real-time conditional branching is also listed. Platform-level, not stated for the 2023 unit. | atom-computing.com |
| Access and pricing | On-premises purchase of AC1000; Partner Program for early access | Vendor reported | The 2023 release said partners could reserve time on systems available in 2024; the existing systems row records this unit as internal. | atom-computing.comthequantuminsider.com |
| Predecessor | Atom Computing 100-qubit prototype system | Vendor reported | CEO blog (2026-10-06) cites the 100-qubit prototype then the 1,200+ qubit AC1000; the 2023 release calls it an order-of-magnitude leap from 100 qubits. | atom-computing.comthequantuminsider.com |
| Roadmap | About 10x more physical qubits per generation; fault-tolerant system with over 1,000 logical qubits by 2029 | Vendor reported | Stated by Atom Computing's CEO in a blog dated 2026-10-06 summarising a Quantum World Congress keynote. | atom-computing.com |
