Abstract

A generalized skew information is defined and then the generalized uncertainty relation is established by the help of the trace inequality which was recently proven by J.I.Fujii. We also point out Theorem 1 in "S.Luo and Q.Zhang, IEEE Trans.IT, Vol.50, pp.1778-1782 (2004)" is incorrect in general, by giving a simple counter-example.
