用Renyi熵表示测不准关系

Formulation of the uncertainty relations in terms of the Renyi entropies

Iwo Bialynicki-Birula

摘要:

位置和动量的量子力学不确定性关系以涉及Renyi熵的不等式的形式表示。这些不等式的证明需要使用由Babenko和Beckner导出的傅立叶变换的(p,q)-范数的精确表达式。类似的不确定性关系推导出的角度和角动量,也为一对互补的可观的N-能级系统。所有这些不确定性关系变得更有吸引力时,表示的对称Renyi熵。

英文摘要:

Quantum mechanical uncertainty relations for position and momentum are expressed in the form of inequalities involving the Renyi entropies. The proof of these inequalities requires the use of the exact expression for the (p,q)-norm of the Fourier transformation derived by Babenko and Beckner. Analogous uncertainty relations are derived for angle and angular momentum and also for a pair of complementary observables in N-level systems. All these uncertainty relations become more attractive when expressed in terms of the symmetrized Renyi entropies.
