Breaking the Optical Barrier: terahertz tech could help enable quantum internet security
Published: 2 June 2026
A new method to distribute cryptographic keys using terahertz waves could help enable secure communication in the quantum-powered internet of the future, researchers say. Engineers from the University of Glasgow are pioneering the development of a new method of quantum key distribution (QKD) using terahertz waves transmitted with a wireless communications system adapted from mobile and wifi networks.
