Quantum, Rowan, and Catellus: Who Is What at Frederick’s Data-Center Campus?
Quantum Frederick is the campus. Catellus develops the broader campus. Rowan develops the Bauxite sites inside it. Here is how the names fit together—and why older records can be confusing.
Last Updated: September 27, 2026
Frederick County’s data-center records use several similar or overlapping names: Quantum Frederick, Quantum Maryland, Quantum Loophole, Catellus, Rowan, and Bauxite.
They do not all describe the same company.
Some names identify the overall campus. Some identify legal entities associated with the land. Others identify companies responsible for developing particular parts of the property.
Here is the short version.
The Short Version
- Quantum Frederick is the name of the overall data-center campus and development project.
- Quantum Maryland LLC is the legal entity associated with ownership of the original campus property.
- Catellus is the sole developer responsible for the broader campus’s day-to-day development and execution.
- Rowan Digital Infrastructure is a separate company developing the Bauxite data-center sites inside the larger campus.
- Quantum Loophole was the project’s original developer but no longer actively manages or develops Quantum Frederick.
The names are connected, but they are not interchangeable.
Quantum Frederick: The Campus
Quantum Frederick is primarily a place and project name.
It refers to the roughly 2,100-acre data-center campus being developed on the former Eastalco aluminum property near Adamstown.
Newer county documents may also call it the Frederick Digital Campus, the Eastalco Data Center Campus, or the Catellus campus. Those names generally describe the same broader development area, although the legal entity or company involved in a particular document may differ.
Calling the entire campus “Rowan” would therefore be inaccurate. Rowan controls and develops specific sites inside the campus, not the entire Quantum Frederick development.
Quantum Maryland LLC: The Landholding Name
Quantum Maryland LLC is a legal entity associated with the campus property.
Frederick County’s adopted planning documents state that Quantum Maryland LLC purchased the approximately 2,122-acre Eastalco property in 2021.
Later county records say that three sites were transferred to Rowan Digital Infrastructure and another site was transferred to Aligned Data Centers. That means the ownership of an individual site should be checked against the deed and date rather than inferred from the campus name.
“Quantum Maryland” should not automatically be treated as another name for Rowan or Catellus. It is a separate legal name appearing in land and development records.
Catellus: The Broader Campus Developer
Catellus is the developer responsible for the larger campus.
Catellus was appointed to lead development of Quantum Frederick in August 2024. A December 2024 settlement then confirmed Catellus as the project’s sole developer, responsible for its day-to-day management and execution.
Frederick County now commonly describes Catellus as the campus’s master developer.
That role includes coordinating the broader development, land planning, infrastructure, government processes, and work affecting the campus as a whole.
Catellus is not simply a new name for Quantum Loophole, and it is not another name for Rowan.
Rowan: The Bauxite Developer
Rowan Digital Infrastructure develops specific data-center sites inside Quantum Frederick.
Rowan calls its Frederick development the Bauxite campus, consisting of Bauxite 1, Bauxite 2, and Bauxite 3.
County records state that three sites within the larger Quantum Frederick property were transferred to Rowan. Rowan describes Bauxite as a hyperscale campus intended for cloud and artificial-intelligence workloads.
Rowan also says it is a developer, not the ultimate data-center operator. It builds the facilities and works with an end user to bring them online.
The practical distinction is:
Catellus develops the broader campus. Rowan develops the Bauxite data-center sites inside that campus.
A Rowan statement about Bauxite should not automatically be attributed to Catellus, Quantum Maryland, or every other project within Quantum Frederick.
Likewise, a Catellus statement about the overall campus does not necessarily describe Rowan’s individual buildings or commitments.
Quantum Loophole: The Original Developer
Quantum Loophole launched and originally developed the Quantum Frederick concept.
The company assembled the project around the former Eastalco site and promoted a model combining land, electrical capacity, water, and fiber infrastructure.
Its role later changed.
In December 2024, Quantum Loophole and the other project parties announced that their management and development dispute had been resolved. Both Quantum Loophole and Catellus stated that Quantum Loophole would no longer have any active involvement in managing or developing Quantum Frederick.
Quantum Loophole did not become Catellus, and it did not become Rowan. It is a separate company whose former role remains visible in older documents.
Why Older Records Can Look Different
A document can be accurate for its date and still describe a role that later changed.
For example:
- Earlier records may identify Quantum Loophole as the campus developer.
- Later records identify Catellus as the sole or master developer.
- Land records may use Quantum Maryland LLC.
- Rowan documents concern the Bauxite sites within the larger campus.
- County documents may use Quantum Frederick, Frederick Digital Campus, Eastalco Data Center Campus, or Catellus campus as broader project descriptions.
The date and named legal entity therefore matter.
The Paper Trail Rule
When reviewing a permit, deed, agreement, site plan, tax record, or public statement:
Follow the entity named on the document. Do not substitute the most familiar project name for the legal party.
Before attributing an obligation or promise, check:
- Which entity is named?
- What property or project does the document cover?
- What role did that entity hold on the document’s date?
- Has ownership or development responsibility changed since then?
That is the simplest way to avoid turning several connected companies into one imaginary organization.
