Isometries of the qubit state space with respect to quantum Wasserstein distances
In this paper we study isometries of quantum Wasserstein distances and
divergences on the quantum bit state space. We describe isometries with respect
to the symmetric quantum Wasserstein divergence $d_{sym}$, the divergence
induced by all of the Pauli matrices. We also give a complete characterization
of isometries with respect to $D_z$, the quantum Wasserstein distance
corresponding to the single Pauli matrix $\sigma_z$.
