Query: CP-violating top quark couplings at future linear $e^+e^-$ colliders   We study the potential of future lepton colliders to probe violation of the
CP symmetry in the top quark sector. In certain extensions of the Standard
Model, such as the two-Higgs-doublet model (2HDM), sizeable anomalous top quark
dipole moments can arise, that may be revealed by a precise measurement of top
quark pair production. We present results from detailed Monte Carlo studies for
the ILC at 500~\GeV{} and CLIC at 380~\gev{} and use parton-level simulations
to explore the potential of high-energy operation. We find that precise
measurements in $e^+e^- \rightarrow t\bar{t}$ production with subsequent decay
to lepton plus jets final states can provide sufficient sensitivity to detect
Higgs-boson-induced CP violation in a viable two-Higgs-doublet model. The
potential of a linear $e^+e^-$ collider to detect CP-violating electric and
weak dipole form factors of the top quark exceeds the prospects of the HL-LHC
by over an order of magnitude.
