EPB Quantum Network Infrastructure

EPB and Qubitekk's Quantum Network launched November 2022 on EPB's substation fiber loops, growing out of a 2015 DOE-funded grid-security partnership with Oak Ridge and Los Alamos national labs. It offers entangled-photon and QKD cryptography infrastructure to researchers and companies; IonQ acquired Qubitekk in December 2024 and is now building an on-site quantum-computing center with EPB, due for commissioning in early 2026.
