We have used the methods of variational calculus for the states that can be written in terms of $N$ MUBs. Our result is valid for any state when $N$ is $d+1$, where $d$ is the dimension of the related system. We have pointed out the fact that our result provides a quantitative criterion for the extendable of MUBs. In addition, we have applied our result to the mutual information of $d+1$ observables conditioned with a classical memory.", "revisions": [ { "version": "v1", "updated": "2020-01-31T12:33:04.000Z" } ], "analyses": { "keywords": [ "entropic uncertainty relation", "optimal upper bound", "mutually unbiased bases", "variational calculus", "mutual information" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable" } } }
