“Florida Atlantic University, Palm Beach State College and Florida LambdaRail established Florida’s first quantum-safe network so universities and colleges could securely share sensitive research data across the state in a post-quantum world.”

A live link between West Palm Beach and Boca Raton
Palm Beach State College and Florida Atlantic University activated the first operating segment of Florida’s planned statewide quantum-safe network on October 15. The link connects PBSC in West Palm Beach with FAU’s Boca Raton campus over Palm Beach County’s dark fiber infrastructure. PBSC President Ava L. Parker announced the launch on October 21 at the college’s Historic Building in West Palm Beach.
IonQ supplies the quantum key distribution technology for the connection. PBSC is leading the first segment with Florida LambdaRail, FAU, Palm Beach County and IonQ, backed by a $1 million FloridaCommerce defense infrastructure grant. The activation turns an initiative announced in April into a live connection between two institutions; it does not mean Florida’s statewide network is complete.
What the quantum link does—and does not do
Quantum key distribution, or QKD, allows two endpoints to establish shared encryption keys using quantum states of light. An attempt to observe the exchange can disturb those states, creating a potential indication of interception. QKD is a way to distribute keys; the announcement describes a connection intended to strengthen data security, not a replacement for every part of the institutions’ cybersecurity systems.
The distinction matters because “quantum-safe” can describe a broader security program than a single QKD link. The PBSC announcement identifies the connected campuses and the technology, but does not specify the link’s bandwidth, the volume or kinds of traffic carried over it, or whether all communications between the institutions use the new connection. Its immediate significance is the deployment of a working QKD segment over existing county fiber.
Three nodes were planned for the first corridor
The April agreement between IonQ and Florida LambdaRail set out an initial corridor linking three research and education institutions from Palm Beach County toward Miami-Dade County. That plan called for using IonQ QKD on Florida LambdaRail’s fiber network. The link now in service marks the first operational step toward that corridor.
Project partners plan to add Miami Dade College and FAU’s John D. MacArthur Campus in Jupiter within the next three months, according to PBSC’s announcement. The Jupiter campus sits near biomedical research institutes named in the project’s plans, including the Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology and the Max Planck Florida Institute for Neuroscience. Those additions remain planned connections, not live segments.
Expansion beyond Palm Beach County still needs support
Florida LambdaRail operates a 1,540-mile dark fiber network on behalf of 13 university partners, according to IonQ’s April announcement. The partners have described broader expansion across that network as a later phase, dependent on funding and participation. A single operational link therefore demonstrates a local deployment, while statewide reach remains a goal rather than a present capability.
For now, the measurable result is a QKD connection between PBSC and FAU’s Boca Raton campus, activated October 15 over Palm Beach County fiber. The next test is whether the planned Jupiter and Miami Dade College links come online on the stated timetable.
