  Generically, non-Standard-Model particles contribute to processes with
order-one charge-parity (CP) violating phases, as CP is not a fundamental
symmetry of nature. The exploration of CP violation becomes therefore a
sensitive search for non-Standard-Model physics. We briefly review the current
status of CP-violation studies in bottom- and charm-quark transitions focusing
on those quantities that are most sensitive to non-Standard-Model contributions
and discuss opportunities and challenges for the next decade and beyond.
