Abstract: 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.

On Strong Converse Theorems for Quantum Hypothesis Testing and Channel Coding [16.207627554776916]
Strong converse theorems refer to the study of impossibility results in information theory. Mosonyi and Ogawa established a one-shot strong converse bound for quantum hypothesis testing. We show that the variational expression of measured R'enyi divergences is a direct consequence of H"older's inequality.

Connecting classical finite exchangeability to quantum theory [69.62715388742298]
Exchangeability is a fundamental concept in probability theory and statistics. We show how a de Finetti-like representation theorem for finitely exchangeable sequences requires a mathematical representation which is formally equivalent to quantum theory.

Limit theorems for Quantum Trajectories [0.0]
We prove Law of Large Numbers (LLN), Functional Central Limit Theorem, Law of Iterated Logarithm and Moderate Deviation Principle. Proof of the LLN is based on Birkhoff's ergodic theorem and an analysis of harmonic functions. The other theorems are proved using martingale approximation of empirical sums.

Correspondence Between the Energy Equipartition Theorem in Classical Mechanics and its Phase-Space Formulation in Quantum Mechanics [62.997667081978825]
In quantum mechanics, the energy per degree of freedom is not equally distributed. We show that in the high-temperature regime, the classical result is recovered.

Quantum Mechanical description of Bell's experiment assumes Locality [91.3755431537592]
Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality. This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment. It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
