Оптические свойства твердых тел: путь к источнику одиночного фотона

The optical properties of solids provide a critical pathway toward realizing reliable single photon sources, which are foundational for quantum communication, computing, and sensing. By understanding and engineering how solids interact with light-through defects, excitons, and band-structure tailoring-we can create materials that emit photons one at a time with high purity and stability. As a result, mastering the optical behavior of solids is not just a fundamental scientific pursuit, but a key step toward transforming single photon sources from laboratory demonstrations into real-world quantum technologies.
