We discuss the decays of the Higgs boson to an $S$-wave vector quarkonium plus a photon. The decay rate is sensitive to both the size and the phase information of the Higgs-charm coupling through quantum interference. We improve the theoretical predictions by resumming logarithms to next-to-leading log accuracy and by calculating relativistic corrections of order $v^2$, where $v$ is the heavy-quark velocity in the quarkonium rest frame. These refinements reduce the theoretical uncertainties in the decay rate and open the door to improved determinations at the LHC of the Higgs-boson Yukawa couplings to charm and bottom quarks.
