Using a highly efficient semiconductor quantum dot photon source, we resolve complex four-photon interference structures previously obscured by noise. We discover "deep fringes" remarkably robust to photon distinguishability and demonstrate that solid-state emitters now outperform probabilistic sources in the multi-photon regime.
