  Polarization and spin correlations have been studied in detail for top quarks
at the LHC, but have been explored very little for the other flavors of quarks.
In this paper we consider the processes $pp\to q\bar{q}$ with $q = b$, $c$ or
$s$. Utilizing the partial preservation of the quark's spin information in
baryons in the jet produced by the quark, we examine possible analysis
strategies for ATLAS and CMS to measure the quark polarization and spin
correlations. We find polarization measurements for the $b$ and $c$ quarks to
be feasible, even with the currently available datasets. Spin correlation
measurements for $b\bar b$ are possible using the CMS Run 2 parked data, while
such measurements for $c\bar c$ will become possible with higher integrated
luminosity. For the $s$ quark, we find the measurements to be challenging with
the standard triggers. We also provide leading-order QCD predictions for the
polarization and spin correlations expected in the $b\bar b$ and $c\bar c$
samples with the cuts envisioned for the above analyses. Apart from
establishing experimentally the existence of spin correlations in $b\bar b$ and
$c\bar c$ systems produced in $pp$ collisions, the proposed measurements can
provide new information on the polarization transfer from quarks to baryons and
might even be sensitive to physics beyond the Standard Model.
