# An uncertainty relation in terms of generalized metric adjusted skew information and correlation measure

An uncertainty relation in terms of generalized metric adjusted skew information and correlation... The uncertainty principle in quantum mechanics is a fundamental relation with different forms, including Heisenberg’s uncertainty relation and Schrödinger’s uncertainty relation. In this paper, we prove a Schrödinger-type uncertainty relation in terms of generalized metric adjusted skew information and correlation measure by using operator monotone functions, which reads, \begin{aligned} U_\rho ^{(g,f)}(A)U_\rho ^{(g,f)}(B)\ge \frac{f(0)^2l}{k}\left| \mathrm {Corr}_\rho ^{s(g,f)}(A,B)\right| ^2 \end{aligned} U ρ ( g , f ) ( A ) U ρ ( g , f ) ( B ) ≥ f ( 0 ) 2 l k Corr ρ s ( g , f ) ( A , B ) 2 for some operator monotone functions f and g, all n-dimensional observables A, B and a non-singular density matrix $$\rho$$ ρ . As applications, we derive some new uncertainty relations for Wigner–Yanase skew information and Wigner–Yanase–Dyson skew information. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals
