Quantum-Secure Fiber-Coupled Underwater Communication for Next-Generation Maritime Defense<\/em><\/p>\n Underwater environments represent a major technological frontier, with critical relevance for military submarines, autonomous underwater vehicles (AUVs), and offshore infrastructure security. Addressing this challenge, DFM has received new funding from the Thomas B. Thriges Foundation for the project “Quantum-Secure Fiber-Coupled Underwater Communication for Next-Generation Maritime Defence.” <\/p>\n The project brings together strong academic partners from the Technical University of Denmark, including the Quantum Network Group, as well as the Gas Photonics Group. Together, the consortium aims to develop the first quantum-grade, deployable single-photon source specifically designed for underwater optical propagation. “Our goal is to develop high-purity quantum materials and integrate them directly into the optical transmission channel for quantum-secure communication in the ocean. This is a highly challenging task, but one with significant impact,” says Dr. Khan, Head of Quantum Materials at DFM. <\/p>\n The project directly addresses key limitations in subsea quantum networks, including photon loss in water, spectral mismatch with the underwater transmission window, and the lack of scalable, quantum-compatible hardware. In addition, the project will collaborate with Danish defense engineering company TERMA to explore pathways for technological integration. <\/p>\n Consortium:<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Quantum-Secure Fiber-Coupled Underwater Communication for Next-Generation Maritime Defense Underwater environments represent a major technological frontier, with critical relevance for military submarines, autonomous underwater vehicles (AUVs), and offshore infrastructure security.
