熵与不确定原理

Entropy and the uncertainty principle

Rupert L. Frank, Elliott H. Lieb

摘要:

本文推广、改进和统一了Rumin和Maassen-Uffink关于量子密度矩阵的经典熵定理.这些定理涉及密度矩阵在两种不同基上的对角线的经典熵。因此,它们提供了一种不确定原理。我们的不等式是尖锐的,因为它们在高温或半经典极限下是精确的。

英文摘要:

We generalize, improve and unify theorems of Rumin, and Maassen--Uffink about classical entropies associated to quantum density matrices. These theorems refer to the classical entropies of the diagonals of a density matrix in two different bases. Thus they provide a kind of uncertainty principle. Our inequalities are sharp because they are exact in the high-temperature or semi-classical limit.
