We develop two general approaches to characterising the manipulation of quantum states by means of probabilistic protocols constrained by the limitations of some quantum resource theory. First, we give a general necessary condition for the existence of a physical transformation between quantum states, obtained using a new resource monotone based on the Hilbert projective metric. In all affine quantum resource theories (e.g. coherence, asymmetry, imaginarity) as well as in entanglement…

Probabilistic Transformations of Quantum Resources.
TLDR
This work introduces a new resource monotone that obeys a very strong type of monotonicity that can rule out all transformations, probabilistic or deterministic, between states in any quantum resource theory, and strengthens previous findings and extends recent no-go theorems.

Fundamental limitations on distillation of quantum channel resources
TLDR
This work establishes universal limitations on the processing of both quantum states and channels, expressed in the form of no-go theorems and quantitative bounds for the manipulation of general quantum channel resources under the most general transformation protocols.
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
Probabilistic Distillation of Quantum Coherence.
TLDR
A fundamental no-go result is proved: Distilling coherence from any full-rank state is impossible even probabilistically, and in some conditions the maximal success probability can vanish suddenly beyond a certain threshold in the distillation fidelity.
One-Shot Operational Quantum Resource Theory.
TLDR
This work analyzes, from a resource-nonspecific standpoint, the optimal efficiency of resource formation and distillation tasks with only a single copy of the given quantum state, thereby establishing a unified framework of one-shot quantum resource manipulation.
Quantum resource theories in the single-shot regime
One of the main goals of any resource theory such as entanglement, quantum thermodynamics, quantum coherence, and asymmetry, is to find necessary and sufficient conditions (NSC) that determine
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.
Reversible Framework for Quantum Resource Theories.
TLDR
The general structure of QRTs is discussed, and it is shown that under a few assumptions, a QRT is asymptotically reversible if its set of allowed operations is maximal, that is, if the allowed operations are the set of all operations that do not generate (asymptotical) a resource.
The resource theory of quantum reference frames: manipulations and monotones
Every restriction on quantum operations defines a resource theory, determining how quantum states that cannot be prepared under the restriction may be manipulated and used to circumvent the
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
