Double parton distribution functions (dPDFs) are a key nonperturbative ingredient in understanding multi-parton interactions. Comparing the dPDF at given momentum fractions $x_1$ and $x_2$ with the product of two single parton distribution functions (PDFs) elucidates correlations or anticorrelations between the two partons. In this talk, we start with a model lightcone wavefunction for the proton and construct the relevant dPDF and PDF. We then leverage methods from quantum information theory to analyze which parton correlations must be rooted in quantum entanglement, and which could arise due to classical correlations. We also detail an algorithm to remove these quantum correlations and analyze their effect on the dPDF. The results are compared to various models from the literature.
