不确定原理与量子费舍尔信息-- II

Uncertainty Principle and Quantum Fisher Information - II

P. Gibilisco, D. Imparato, T. Isola

摘要:

海森堡和薛定谔不确定原理给出了在状态$ρ$中方差积$Var_ρ(A)\cdot Var_ρ(B)$的下界,如果可观测量$A,B$不相容,即交换子$[A,B]$不为零。本文证明了一个薛定谔形式的不确定原理,其中方差积$Var_ρ(A)\cdot Var_ρ(B)$的界依赖于相对于任意量子形式的Fisher信息的离散子$[ρ,A]$和$[ρ,B]$所跨越的面积.

英文摘要:

Heisenberg and Schr{ö}dinger uncertainty principles give lower bounds for the product of variances $Var_ρ(A)\cdot Var_ρ(B)$, in a state $ρ$, if the observables $A,B$ are not compatible, namely if the commutator $[A,B]$ is not zero. In this paper we prove an uncertainty principle in Schr{ö}dinger form where the bound for the product of variances $Var_ρ(A)\cdot Var_ρ(B)$ depends on the area spanned by the commutators $[ρ,A]$ and $[ρ,B]$ with respect to an arbitrary quantum version of the Fisher information.
