Chattanooga’s municipal utility has opened a $22 million IonQ quantum computer beside its existing quantum network, creating a rare commercial test bed whose value now depends on useful results rather than infrastructure claims. EPB launched the Forte Enterprise system on September 18 and says outside customers will be able to buy access starting in early October.
Evidence note: researched September 20, 2026, from EPB and IonQ materials plus independent reporting by the Chattanooga Times Free Press, Quantum Litmus, and the American Public Power Association. Toolsfine did not use the system or independently benchmark its hardware, network, economics, or power-grid applications. Performance figures and “first” claims are attributed to their sources.

What opened in Chattanooga
EPB announced that the rack-mounted Forte Enterprise system is online at its downtown Quantum Center. The municipal electricity and communications provider already operates a commercial quantum network, launched in 2023, over dedicated fiber infrastructure. EPB describes the combined facility as America’s first commercial quantum computing and networking hub.
The first users will be eight graduate researchers in an EPB fellowship funded by a $4 million National Institute of Standards and Technology grant. Their initial work focuses on algorithms intended to improve power-grid circuit optimization. The University of Tennessee at Chattanooga is scheduled to become the first outside customer, while EPB says it is arranging an initial project with Vanderbilt University.
Independent local reporting adds useful detail. The Chattanooga Times Free Press reported that customers will rent computer time, run algorithms, review results, and return to their own organizations. The paper also confirmed the $22 million cost and reported that EPB’s earlier quantum-networking service has already recovered its investment, according to utility officials.
What the Forte Enterprise system provides
IonQ’s system uses trapped ions as qubits and lasers to prepare, manipulate, and measure them. The company’s current specification page lists 36 physical qubits, all-to-all connectivity, a 0.02% one-qubit gate error, and a 0.4% two-qubit gate error. Those are vendor figures, not measurements produced by the Chattanooga launch.
The machine is designed to fit standard data-center workflows rather than requiring every customer to build a dedicated quantum laboratory. The original April 2025 IonQ agreement described it as a low-energy, rack-mounted system and committed IonQ to an office in Chattanooga for application support and training.
Thirty-six qubits do not make the computer a general replacement for classical servers. Near-term quantum machines are specialized and error-prone, so useful work normally combines short quantum circuits with classical optimization, simulation, or data-processing steps. The facility is best understood as research and development infrastructure for testing workflows, not a finished shortcut to faster answers.
Why combine quantum computing and networking?
Quantum computing and quantum networking solve different problems. The computer processes quantum circuits in one location. The network lets researchers test how quantum states, keys, or future distributed quantum resources could move across fiber. Putting both in one center reduces coordination friction for teams building experiments that span hardware, software, and communications.
That combination could be useful for utilities, universities, cybersecurity teams, and developers that want access to physical equipment without buying a system. It also gives Chattanooga a place to train staff and evaluate integration questions such as job scheduling, classical-quantum orchestration, network control, and secure operations.
Still, proximity does not automatically create a distributed quantum computer. It does not show that the network can scale fault-tolerant computation across remote processors, nor that a commercial workload is cheaper or faster than a strong classical approach. The infrastructure enables experiments; it is not evidence that every proposed application will work.
What is proven—and what is not
The confirmed change is physical: a purchased quantum computer has moved from a planned installation to an operating facility with named initial users and an announced commercial opening date. The American Public Power Association independently reported the launch and the planned university access.
The evidence stops short of a business or scientific breakthrough. Quantum Litmus noted that EPB disclosed no new processor benchmark, useful grid calculation, independent acceptance test, or customer economics. EPB has also not published general pricing, queue expectations, service-level commitments, or a result comparing the system with classical alternatives.
Organizations evaluating the hub should ask for a benchmark matched to their own problem, including error mitigation, repeated-run variance, classical preprocessing, post-processing, staff time, and total cost. A fair test needs a serious classical baseline and a success criterion defined before the quantum run.
Practical takeaways for prospective users
- Start with a narrow research question: choose an optimization, chemistry, machine-learning, or networking problem with a measurable output.
- Budget for hybrid work: quantum execution is only one part of the pipeline; classical code and domain expertise remain essential.
- Request reproducible evidence: record backend settings, run counts, error-mitigation methods, and the classical comparison.
- Separate learning value from production value: training a team may be worthwhile even when a workload has no quantum advantage yet.
- Check security boundaries: understand what data enters the service, what leaves it, and how jobs, credentials, and results are isolated.
Bottom line
Chattanooga now has tangible quantum infrastructure: an installed 36-qubit system, an existing fiber network, named research users, and a near-term commercial access plan. That is more meaningful than a roadmap slide. It is not yet proof of lower costs, faster grid optimization, or broad quantum advantage. The next credible milestone will be a reproducible workload showing where the combined hub performs better—or teaches users something they could not learn as efficiently elsewhere.
