Colloquium: Incompatible measurements in quantum information science
Some measurements in quantum mechanics disturb each other. This has puzzled physicists
since the formulation of the theory, but only in recent decades has the incompatibility of …

[PDF][PDF] Mitigation of readout noise in near-term quantum devices by classical post-processing based on detector tomography
We propose a simple scheme to reduce readout errors in experiments on quantum systems
with finite number of measurement outcomes. Our method relies on performing classical …

General resource theories in quantum mechanics and beyond: operational characterization via discrimination tasks
We establish an operational characterization of general convex resource theories—
describing the resource content of not only states but also measurements and channels …

All sets of incompatible measurements give an advantage in quantum state discrimination
Some quantum measurements cannot be performed simultaneously; ie, they are
incompatible. Here we show that every set of incompatible measurements provides an …

Quantifying quantum resources with conic programming
Resource theories can be used to formalize the quantification and manipulation of resources
in quantum information processing such as entanglement, asymmetry and coherence of …

Robustness of measurement, discrimination games, and accessible information
We introduce a resource theory of measurement informativeness. This allows us to define an
associated quantifier, which we call the robustness of measurement. It describes how much …

Operational relevance of resource theories of quantum measurements
For any resource theory it is essential to identify tasks for which resource objects offer
advantage over free objects. We show that this identification can always be accomplished …

Complete resource theory of quantum incompatibility as quantum programmability
Measurement incompatibility describes two or more quantum measurements whose
expected joint outcome on a given system cannot be defined. This purely nonclassical …

Application of the resource theory of channels to communication scenarios
We introduce a resource theory of channels relevant to communication via quantum
channels, in which the set of constant channels—useless channels for communication tasks …
