Hybrid diamond chip strengthens light-qubit interactions

Researchers demonstrated a hybrid photonic platform that integrates quantum emitters with photonic devices on a diamond substrate combined with gallium phosphide (GaP). The chip enables reliable control of photon interactions with quantum information carriers and could make long-distance quantum networks more practical.
