"Researchers Demonstrate Secure Information Transfer Using Spatial Correlations in Quantum Entangled Beams of Light"
University of Oklahoma researchers led a study recently published in Science Advances that demonstrates using spatial correlations in quantum entangled light beams to encode information and enable its secure transmission. Light can be used to encode information for high-speed data transmission, long-distance communication, and other purposes. For secure communication, encoding large amounts of information in light presents additional challenges for ensuring the privacy and integrity of the transferred data. The idea of the project is to encode large amounts of information using the spatial properties of light, similar to how an image contains information. However, this should be done in a way compatible with quantum networks for secure information transfer. This article continues to discuss the demonstration of secure information transfer using spatial correlations in quantum entangled beams of light.
