Abstract
We report the first observation of single top quark production using ppbar collision data with sqrt{s}=1.96 TeV collected by the CDF II and D0 detectors at Fermilab. The significance of both the observed CDF and D0 data is 5.0 standard deviations, and the expected sensitivity is in excess of 5.9 and equal to 4.5 standard deviations, respectively. The single top production cross section and the CKM matrix element value |V_{tb}| have been measured.
