In the classical setting, we compute the recent canonical divergence on the manifold of positive measures and prove that it coincides with the classical $\\alpha$-divergence. In the quantum framework, such a divergence is evaluated for the quantum $\\alpha$-connections on the manifold of positive definite matrices. Also, in this case we obtain that the recent canonical divergence is the quantum $\\alpha$-divergence.", "revisions": [ { "version": "v1", "updated": "2019-07-25T15:07:13.000Z" } ], "analyses": { "keywords": [ "canonical divergence", "connections", "quantum framework", "dualistic structure", "smooth manifold" ], "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable" } } }
