Lumen Technologies (NYSE: LUMN) announced a dual initiative to advance quantum network transport and post-quantum cryptography (PQC) for enterprises. The company will fund research with The Ohio State University (OSU) to study long-range single-photon and entangled-state propagation over deployed optical fiber, as well as quantum sensing protocols that monitor seismic shifts and cable strain. At the same time, Lumen is embedding Fortinet’s FortiOS/FortiGate PQC libraries—standardized under FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA)—into its managed Secure Access Service Edge (SASE) solution, offering a crypto-agile path away from RSA and elliptic-curve cryptography. A customer preview of the PQC-enabled SASE begins in November 2026, with general availability planned for January 2027. The effort also includes a pilot with Emerald AI to steer AI workloads based on power-grid availability. 1
