  An overview of recent measurements of inclusive and differential single top
quark cross sections at 13 TeV with the CMS experiment is given in this note.
This includes measurements targeting the $t$-channel and tW production modes
resulting in inclusive cross sections of
$\sigma_{t\mathrm{\mbox{-}ch.}}=238\pm32~\mathrm{pb}$ and
$\sigma_\mathrm{tW}=63.1\pm6.6~\mathrm{pb}$ respectively. In addition, the
$t$-channel cross section has been measured differentially as a function of the
top quark transverse momentum and rapidity. The results are found in agreement
with the standard model expectations. Furthermore, a search for single top
quark production in association with a Z boson is detailed which yields an
observed (expected) significance of 3.7 (3.1) standard deviations.
