Physicists have made a major leap in our understanding of quantum entanglement by fully mapping out the statistics it can produce – essentially decoding the language of the quantum world.

This breakthrough reveals how the bizarre but powerful correlations in quantum systems can be used to test, secure, and certify the behavior of quantum devices, all without knowing their inner workings. The ability to self-test even partially entangled systems now opens doors to more robust quantum communication, encryption, and computing methods. It’s a game-changer for both fundamental physics and real-world quantum tech.
