We introduce and apply Hilbert's projective metric in the context of quantum information theory. The metric is induced by convex cones such as the sets of positive, separable or positive partial transpose operators. It provides bounds on measures for statistical distinguishability of quantum states and on the decrease of entanglement under protocols involving local quantum operations and classical communication or under other cone-preserving operations. The results are formulated in terms of…

The Quantum Wasserstein Distance of Order 1
TLDR
This work proposes a generalization of the Wasserstein distance of order 1 to the quantum states of $n$ qudits and derives bounds on the contraction coefficients of shallow quantum circuits and of the tensor product of one-qudit quantum channels with respect to the proposed distance.

Markov operators on cones and non-commutative consensus
TLDR
A characterization of the contraction rate of an abstract Markov operator on a cone is given, which extends classical formulæ obtained by Dœblin and Dobrushin in the case of Markov matrices.
Quantum Fidelity and the Bures Metric in Operator Algebras
This dissertation undertakes the study of quantum fidelity, a distinguishability measure in the context of quantum mechanics, from the operator algebraic viewpoint. The notion of fidelity provides a
Extending quantum operations
For a given set of input-output pairs of quantum states or observables, we ask the question whether there exists a physically implementable transformation that maps each of the inputs to the
An information-theoretic treatment of quantum dichotomies
TLDR
The rate at which pairs of states can be transformed into each other is given by the ratio of their relative entropies, and applications to the resource theories of athermality and coherence are discussed.
Projective robustness for quantum channels and measurements and their operational significance
Recently, the projective robustness of quantum states was introduced in (Regula 2022 Phys. Rev. Lett. 128 110505). This demonstrates that the projective robustness is a useful resource monotone and
Projective robustness for quantum channels and measurements and their operational significance
Recently, the projective robustness of quantum states has been introduced in [arXiv:2109.04481(2021)]. It shows that the projective robustness is a useful resource monotone and can comprehensively
Base norms and discrimination of generalized quantum channels
TLDR
This work obtains a necessary and sufficient condition under which an optimal 1-tester for discrimination of quantum channels exists, such that the input state is maximally entangled.
Convex geometry of quantum resource quantification
We introduce a framework unifying the mathematical characterisation of different measures of general quantum resources and allowing for a systematic way to define a variety of faithful quantifiers

Distinguishability and Accessible Information in Quantum Theory
TLDR
This document focuses on translating various information-theoretic measures of distinguishability for probability distributions into measures of distin- guishability for quantum states, and gives a way of expressing the problem so that it appears as algebraic as that of the problem of finding quantum distinguishability measures.
Asymptotic Error Rates in Quantum Hypothesis Testing
We consider the problem of discriminating between two different states of a finite quantum system in the setting of large numbers of copies, and find a closed form expression for the asymptotic
Quantum entanglement
All our former experience with application of quantum theory seems to say that what is predicted by quantum formalism must occur in the laboratory. But the essence of quantum formalism— entanglement,
Entanglement purification via separable superoperators
TLDR
This work uses the fact that every EPP is a separable superoperator to give a new upper bound on the rate of EPPs on Bell- diagonal states, and thus on the capacity of Bell-diagonal channels.

We introduce quantum versions of the χ2-divergence, provide a detailed analysis of their properties, and apply them in the investigation of mixing times of quantum Markov processes. An approach

The Perron-Frobenius Theorem says that if A is a nonnegative square matrix some power of which is positive, then there exists an x0 such that Anx/‖Anx‖ converges to xn for all x > 0. There are many
Distinguishability of Quantum States Under Restricted Families of Measurements with an Application to Quantum Data Hiding
TLDR
Lower bounds on the performance of various POVMs acting on a single system such as the isotropic POVM, and spherical 2 and 4-designs are provided, and it is shown how these bounds can lead to certainty relations.
Quantum Computation and Quantum Information
