  We use exact Quantum Monte Carlo techniques to study the properties of
quantum droplets in two-component bosonic mixtures with contact interactions in
one spatial dimension. We systematically study the surface tension, the density
profile and the breathing mode as a function of the number of particles in the
droplet and of the ratio of coupling strengths between intra-species repulsion
and inter-species attraction. We find that deviations from the predictions of
the generalized Gross-Pitaevskii equation are small in most cases of interest.
