The experiment achieved Hong–Ou–Mandel interference with a visibility of 0.65 ± 0.14 without spectral or temporal modification. By spectrally tuning quantum dots to 12.5 K to match the cesium photon wavelength at ~917 nm, the team achieved a spectral overlap of 0.88. This hybrid quantum architecture pairs quantum dots (bright, high-rate photon sources) with atomic systems (photon storage and synchronization), potentially enabling distributed quantum networks, scalable quantum computers, and a functional quantum internet. ## Full article daily.dev links to this article rather than hosting it.
