We study metric properties of symmetric divergences on Hermitian positive definite matrices. In particular, we prove that the square root of these divergences is a distance metric. As a corollary we obtain a proof of the metric property for Quantum Jensen-Shannon-(Tsallis) divergences (parameterized by α∈[0, 2]). When specialized to α= 1, we obtain as a corollary a proof of the metric property of the Quantum Jensen-Shannon divergence that was conjectured by Lamberti et al.(2008)[13], and recently also proved by Virosztek (2019)[28]. A more intricate argument also establishes metric properties of Jensen-Rényi divergences (for α∈(0, 1)); this argument develops a technique that may be of independent interest.
