| Abstract: | 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]. |
| Keywords: | Heisenberg uncertainty relation Wigner-Yanase-Dyson skew information Operator monotone function Quantum Fisher information |
