"Revolutionary Quantum Device: Generating Single Photons and Encoding Information"

Scientists at Los Alamos National Laboratory have developed a new quantum light source that generates circularly polarized single photons without the need for an external magnetic field. By stacking two atomically thin materials and creating nanometer-scale indentations, the researchers were able to control the polarization state of the emitted photons. This breakthrough could have significant implications for quantum cryptography and communication, as it combines the generation of single photons with the ability to introduce polarization, paving the way for encoding quantum information into the photon stream.
