    "abstract": "The realisation of a triggered entangled photon source will be of great\nimportance in quantum information, including for quantum key distribution and\nquantum computation. We show here that: 1) the source reported in ``A\nsemiconductor source of triggered entangled photon pairs\u0027\u0027[1. Stevenson et al.,\nNature 439, 179 (2006)]} is not entangled; 2) the entanglement indicators used\nin Ref. 1 are inappropriate, relying on assumptions invalidated by their own\ndata; and 3) even after simulating subtraction of the significant quantity of\nbackground noise, their source has insignificant entanglement.",
