【 摘 要 】

We show that an uncertainty relation for Wigner-Yanase-Dyson skew information proved by Yanagi (2010) [10] can hold for an arbitrary quantum Fisher information under some conditions. This is a refinement of the result of Gibilisco and Isola (2011) [4]. (C) 2011 Elsevier Inc. All rights reserved.
