PT Journal AU Xu, X Wong, CW TI Quantum optics: Correlations on a chip SO Nature Photonics JI Nat. Photon. PY 2012 BP 75 EP 76 VL 6 DE fromIPMRAS AB Researchers have developed a semiconductor structure capable of supporting quantum correlations between photons and strong single-photon nonlinearities, thus paving the way for the development of chip-based devices for quantum secure communications and quantum information processing.
