The range of a quantum measurement is the set of output probability distributions that can be produced by varying the input state. We introduce data-driven inference as a protocol that, given a set of experimental data as a collection of output distributions, infers the quantum measurement which is, i) consistent with the data, in the sense that its range contains all the distributions observed, and, ii) maximally noncommittal, in the sense that its range is of minimum volume in the space of… Expand

Data-driven inference of physical devices: theory and implementation
It is shown that, even without any knowledge about the tomographic apparatus, it is still possible to infer the unknown device to a high degree of precision, solely relying on the observed data. Expand
Algebraic and Statistical ways into Quantum Resource Theories
Quantum information science is one of the most active, intellectually stimulating, and technologically promising areas in science. It offers a unique opportunity to engage in a wide variety ofExpand
Experimental Self-Characterization of Quantum Measurements.
This work reports a self-characterization method of quantum measurements based on reconstructing the response range-the entirety of attainable measurement outcomes, eliminating the reliance on known states. Expand
Extension of the Alberti-Ulhmann criterion beyond qubit dichotomies
The Alberti-Ulhmann criterion is generalized to the case of arbitrary number of qubit or qutrit states and an analogous result is derived for the cases of qu bit orqutrit measurements with arbitrarily number of elements. Expand

Device-independent tests of quantum channels
A device-independent framework for testing quantum channels is developed and it is shown that extremal correlations are always achieved by orthogonal encodings and measurements, irrespective of whether or not the channel preserves commutativity. Expand
Nonlocal correlations as an information-theoretic resource
It is well known that measurements performed on spatially separated entangled quantum systems can give rise to correlations that are nonlocal, in the sense that a Bell inequality is violated. TheyExpand
Evidence for the epistemic view of quantum states: A toy theory
We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in aExpand
Clean positive operator valued measures
In quantum mechanics the statistics of the outcomes of a measuring apparatus is described by a positive operator valued measure (POVM). A quantum channel transforms POVMs into POVMs, generallyExpand
Device-Independent Tests of Quantum Measurements.
The main result is to provide a closed-form, full characterization of the set of input-output correlations that can be generated by an arbitrarily given quantum measurement, and to discuss its geometrical interpretation. Expand
Quantum-Bayesian Coherence
It is argued that the Born Rule should be seen as an empirical addition to Bayesian reasoning itself, and how to view it as a normative rule in addition to usual Dutch-book coherence is shown. Expand
Testing axioms for quantum theory on probabilistic toy-theories
This paper tests a set of operational postulates to be considered for axiomatizing Quantum Theory on some nonquantum probabilistic models, and examines how each model violates some of the proposed postulates, when and how teleportation can be achieved, and analyzes other interesting connections between these postulate violations.

Information processing in generalized probabilistic theories
A framework in which a variety of probabilistic theories can be defined, including classical and quantum theories, and many others, is introduced, and a tensor product rule for combining separate systems can be derived. Expand
Quantum majorization and a complete set of entropic conditions for quantum thermodynamics
A quantum-mechanical generalization of majorization is used to derive a complete set of necessary and sufficient conditions for thermal transformations of quantum states, based on natural physical principles, namely, energy conservation, the existence of equilibrium states, and the requirement that quantum coherence be accounted for thermodynamics.

Comparison of Quantum Statistical Models: Equivalent Conditions for Sufficiency
A family of probability distributions (i.e. a statistical model) is said to be sufficient for another, if there exists a transition matrix transforming the probability distributions in the former toExpand
