Hybrid nanoantennas enable light capture from diamond defects

Researchers at the Hebrew University of Jerusalem and the Humboldt University in Berlin have developed a way to capture nearly all the light emitted from tiny diamond defects known as color centers. By placing nanodiamonds into specially designed hybrid nanoantennas with extreme precision, the team achieved record photon collection at room temperature—a necessary step for quantum technologies such as quantum sensors, and quantum-secured communications.
