Single-photon source
Hi, thanks for pointing out the error. In Wikipedia references are usually defined where they are used in the text, not at the bottom where they are shown in the article. See Help:Referencing for beginners for details. I fixed your change in Single-photon source (you can see the changes in the article history). --mfb (talk) 19:03, 2 November 2018 (UTC)
