IonQ Forte Enterprise at EPB
IonQ Forte Enterprise at EPB is a trapped ions quantum computer operated by EPB in USA. It has 36 physical qubits. It ranks 5 of 15 trapped ion machines in this table by physical qubit count. 4 sourced specs are in the spec sheet. 1 published benchmark or milestone record are listed below, each marked by who measured it.
Also known as EPB Quantum Center IonQ system
IonQ Forte Enterprise launched by EPB at its Quantum Center in Chattanooga on 2026-09-18, with commercial access from early October 2026. The first users are the EPB Quantum Computing Fellows, with UTC and Vanderbilt as anchor academic clients. Qubit count and #AQ come from trade coverage, not the EPB release.
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 | IonQ Forte Enterprise, data-center version of the Forte-class system | Vendor reported | IonQ describes Forte Enterprise as the first generation of data center deployable IonQ computers. | epb.comionq.com |
| Qubit type | 171Yb+ hyperfine ion | Vendor reported | Family-wide fact for IonQ Forte-class systems; EPB release does not name the ion species. | ionq.comdocs.aws.amazon.com |
| Access and pricing | On-premises at EPB Quantum Center; commercial service from early October 2026, fellows and universities first | Vendor reported | EPB Quantum Computing Fellows use it first, then University of Tennessee at Chattanooga as first customer; no price is published. | epb.com |
| Predecessor | IonQ Forte Enterprise at QuantumBasel | Vendor reported | Same Forte Enterprise product; the Basel unit was commissioned in December 2024 and is the earlier deployment. | thequantuminsider.comepb.com |
Published benchmark figures
These are numbers the builder or a paper reports for this machine, not results from a common test. The basis column says who measured them. What the metrics mean and why they are not comparable across technologies.
| Metric | Value | Measured | Basis | Note | Source |
|---|---|---|---|---|---|
| Algorithmic qubits (#AQ) | 36 | 2026-09-18 | Vendor reported | Trade report on EPB launch states #AQ 36 for the trapped-ion unit; EPB release gives no figure | quantumcomputingreport.com |
