Uncertainty Relation on Generalized Wigner-Yanase-Dyson Skew Information
We give a trace inequality related to the uncertainty relation of generalized Wigner-Yanase-Dyson skew information which is two parameter’s extension of our result in [12].
متن کاملWigner-Yanase-Dyson Skew Information And Uncertainty Relation
We give a trace inequality related to the uncertainty relation of Wigner-YanaseDyson skew information. This inequality corresponds to a generalization of the uncertainty relation derived by S.Luo [8] for the quantum uncertainty quantity excluding the classical mixture. Finally we show a counter-example of the uncertainty relation related to WignerYanase-Dyson skew information given in [6] recen...
متن کاملUncertainty Relation Based on Wigner-Yanase-Dyson Skew Information with Quantum Memory
We present uncertainty relations based on Wigner–Yanase–Dyson skew information with quantum memory. Uncertainty inequalities both in product and summation forms are derived. It is shown that the lower bounds contain two terms: one characterizes the degree of compatibility of two measurements, and the other is the quantum correlation between the measured system and the quantum memory. Detailed e...
متن کاملSchrödinger uncertainty relation, Wigner-Yanase-Dyson skew information and metric adjusted correlation measure
In this paper, we give Schrödinger-type uncertainty relation using the WignerYanase-Dyson skew information. In addition, we give Schrödinger-type uncertainty relation by use of a two-parameter extended correlation measure. We finally show the further generalization of Schrödinger-type uncertainty relation by use of the metric adjusted correlation measure. These results generalize our previous r...
