Recently, in the paper (Liu and Luo, Phys. Rev. A 104, 052227, 2021) a very beautiful measure of the unsharpness (fuzziness) of the observables constructed via uncertainty is discussed. This measure does not depend on the values of the outcomes and can measure the intrinsic unsharpness of the observables. In this work, we also quantify the unsharpness of observables in an outcome-independent way. But our approach is operationally motivated and different than the approach of the paper (Liu and…

Indefinite causal order enables perfect quantum communication with zero capacity channels

Quantum mechanics is compatible with scenarios where the relative order between two events can be indefinite. Here we show that two independent instances of a noisy process can behave as a perfect

Information leak and incompatibility of physical context: A modified approach

This work has introduced a generalization and modification to their approach in more general and convenient way, such that this idea is well-defined for generic measurements, without these limitations.

Semi-device-independent self-testing of unsharp measurements

A prepare-transform-measure scenario in which two-outcome unsharp measurements outperform their sharp counterparts, as well as any stochastic strategy involving dichotomic projective measurements, and a method, based on semidefinite programming, for bounding quantum correlations in scenarios with sequential measurements of length two.

Complete Resource Theory of Quantum Incompatibility as Quantum Programmability.

This Letter characterize incompatibility in terms of programmable measurement devices and the general notion of quantum programmability, which refers to the temporal freedom a user has in issuing programs to a quantum device.

The Resource Theory of Entanglement

The first result presents a new approach for improving standard witnessing techniques by using additional information obtained within witnessing experiments and thus, cope with unexpected experimental imperfections, and the second result illustrates the use of entanglement witnessing in construction of measures ofEntanglement that are independent of the specific description of measurement devices similar to a Bell scenario.

When is a quantum measurement

The measurement of a quantum system is not consummated until irreversible processes have destroyed all phase coherence between different possible outcomes of that measurement. It is inconsistent to

Quantum measuring processes of continuous observables

The purpose of this paper is to provide a basis of theory of measurements of continuous observables. We generalize von Neumann’s description of measuring processes of discrete quantum observables in

Uncertainty relations for positive-operator-valued measures

How much unavoidable randomness is generated by a positive-operator-valued measure (POVM)? We address this question using two complementary approaches. First, we study the variance of a real variable
