Data processing for qubit state tomography: An information geometric approach

Akio Fujiwara, Koichi Yamagata

A statistically feasible data post-processing method for the conventional qubit state tomography is studied from an information geometrical point of view. It is shown that the spac…

Information geometry of sandwiched Rényi $α$ -divergence

Kaito Takahashi, Akio Fujiwara

Information geometrical structure $(g^{(D_{α})}, \nabla^{(D_{α})}, \nabla^{(D_{α}) *})$ induced from the sandwiched Rényi $α$ -divergence $D_α(ρ\|σ):=\frac{1}{α(α-1)}\log\,{\rm Tr} \left(σ^…
