Measurements of single top-quark production at the LHC

This article summarizes the status of measurements of single top-quark production at the LHC operating at a center-of-mass energy of 7 TeV. As of Summer 2011, the highlights in single-top physics at CERN have been the observation of the t-channel production mode by the ATLAS collaboration with a significance of 7.6 standard deviations and first indications of $Wt$ associated production by CMS with 2.7 standard deviations. The measured cross sections are in good agreement with the predictions by the standard model.
