A limit of the quantum Rényi divergence

Nilanjana Datta, Felix Leditzky

Recently, an interesting quantity called the quantum Rényi divergence (or 'sandwiched' Rényi relative entropy) was defined for pairs of positive semi-definite operators ρ and σ. It depends on a parameter α and acts as a parent quantity for other relative entropies which have important operational significance in quantum information theory: the quantum relative entropy and the min- and max-relative entropies. There is, however, another relative entropy, called the 0-relative Rényi entropy, which plays a key role in the analysis of various quantum information-processing tasks in the one-shot setting. We prove that the 0-relative Rényi entropy is obtainable from the quantum Rényi divergence only if ρ and σ have equal supports. This, along with existing results in the literature, suggests that it suffices to consider two essential parent quantities from which operationally relevant entropic quantities can be derived—the quantum Rényi divergence with parameter α ⩾ 1/2, and the α-relative Rényi entropy with α ∈ [0, 1).

Uniform continuity bound for sandwiched Rényi conditional entropy

Ashutosh S. Marwah, Frédéric Dupuis

We prove a simple uniform continuity bound for the sandwiched Rényi conditional entropy for α ∈ [1/2, 1) ∪ (1, ∞], which is independent of the dimension of the conditioning system.

Rescaled ♮ α -Rényi divergences of all real orders

Yūki Seo

In this paper, inspired by the idea due to Takahashi and Fujiwara, for density matrices ρ,σ, we define the rescaled ♮α-Rényi divergence Dˆα(ρ||σ):=1α(α−1)log⁡Tr[σ♮αρ] of all real orders α∈R of ρ from σ, where σ♮αρ:=σ1/2(σ−1/2ρσ−1/2)ασ1/2 for α∈R, and study its properties such as the positivity, the data processing inequality, continuity on R and jointly convexity. Moreover, we determine the order relation among Dˆα(ρ||σ), the rescaled sandwiched α-Rényi divergence D~α(ρ||σ) and the rescaled α-Rényi divergence Dα(ρ||σ).

Uhlmann’s Theorem for Measured Divergences

Kun Fang, Hamza Fawzi, Omar Fawzi

Uhlmann’s theorem is a cornerstone of quantum information theory, stating that for any quantum state ρABand any state σA, there exists an extension σABof σAsuch that the fidelity between ρABand σABequals the fidelity between their marginals ρAand σA. This property underpins many results and applications in quantum information science. In this work, we generalize Uhlmann’s theorem to a broad class of measuredf-divergences, including the measured α-Rényi divergences for all α ≥ 0. The well-known Uhlmann’s theorem for the fidelity corresponds to the special case α = 1/2. Since most commonly used quantum Rényi divergences, including the Petz and sandwiched Rényi divergences, cannot satisfy this property (except for degenerate cases), this fundamentally distinguishes measuredf-divergences from other quantum divergences and highlights their unique mathematical structure.
