由态划分定义的n进制量子信息

Quantum information in base n defined by state partitions

Karl Svozil

摘要:

我们将“nit”定义为量子信息的基数n度量,其基于与n元可观测量的结果相关联的状态划分,并且对于n>2,其基本上不可约为二进制编码。讨论了纠缠多粒子态中该测度的性质。k个粒子指定k个尼特,使得具有n个可能结果的可观测量的k个相互交换的测量足以确定信息。

英文摘要:

We define a "nit" as a radix n measure of quantum information which is based on state partitions associated with the outcomes of n-ary observables and which, for n>2, is fundamentally irreducible to a binary coding. Properties of this measure for entangled many-particle states are discussed. k particles specify k nits in such a way that k mutually commuting measurements of observables with n possible outcomes are sufficient to determine the information.
