Physicists at the University of the Witwatersrand and Universitat Autònoma de Barcelona have demonstrated methods to shape photons across space and time to create high-dimensional quantum states for advanced communication and imaging applications. The breakthrough, published in Nature Photonics, uses on-chip photonics and structured light techniques, though long-distance transmission remains a challenge researchers are addressing through topological quantum approaches.
