Sanov定理的另一个量子版本
Another quantum version of Sanov theorem
AI总结:
针对现有量子Sanov定理与经典情形不一致的问题,通过引入经验分布的量子类比,提出了Sanov定理的另一个量子版本。
摘要:
我们研究如何将Sanov定理扩展到量子设定。尽管Bjelakovic等人(Commun. Math. Phys., 260, p.659 (2005))提出了Sanov定理的一个量子版本,但其陈述的经典情形与Sanov定理并不相同,因为Sanov定理讨论的是经验分布与真实分布不同时经验分布的行为,而他们研究的是一个与量子假设检验相关的问题,其经典版本可由经典Sanov定理证明。我们通过考虑经验分布的量子类比,提出了Sanov定理的另一个量子版本。
英文摘要:
We study how to extend Sanov theorem to the quantum setting. Although a quantum version of the Sanov theorem was proposed in Bjelakovic et al (Commun. Math. Phys., 260, p.659 (2005)), the classical case of their statement is not the same as Sanov theorem because Sanov theorem discusses the behavior of the empirical distribution when the empirical distribution is different from the true distribution, but they studied a problem related to quantum hypothesis testing, whose classical version can be shown by classical Sanov theorem. We propose another quantum version of Sanov theorem by considering the quantum analog of the empirical distribution.
