We study the feasibility of detecting quark matter cores in merging neutron
stars with ground-based gravitational-wave detectors. We focus on models with a
sharp hadronic/quark matter interface, and assume a uniform distribution of
neutron stars in the mass range $[1,2] M_odot$. We find that the existence of
quark matter cores can be confirmed at the 70% confidence level with as few as
several tens of detections. Likewise, with such a sample, we find that some
models of quark matter cores can be excluded with high confidence.
