"Cutting-Edge Device Harnesses Quantum Illumination for Single Photon Generation and Information Encoding"

Scientists at Los Alamos National Laboratory have developed a new technique to generate circularly polarized single photons, a crucial step towards quantum communication and information processing. By using nanometer-scale indentations on a stack of atomically thin materials, the researchers were able to emit circularly polarized light without the need for an external magnetic field. This breakthrough could pave the way for advancements in quantum cryptography, communication, and the development of a hyper-secure quantum internet.
