It is one of the peculiar features of quantum physics that some sets of measurements are
incompatible in the sense that they cannot be performed simultaneously. Incompatibility is …

Measurement incompatibility stipulates the existence of quantum measurements that cannot
be carried out simultaneously on single systems. We show that the set of input-output …

A dimension witness provides a device-independent certification of the minimal dimension
required to reproduce the observed data without imposing assumptions on the functioning of …

Complications in preparing and preserving quantum correlations stimulate recycling of a
single quantum resource in information processing and communication tasks multiple times …

Preparing and measuring physical systems are the operational building blocks of any
physical experiment, and to describe them is the first purpose of any physical theory …

The so-called preparation uncertainty that occurs in the quantum world can be understood
well in purely operational terms, and its existence in any given theory, perhaps differently …

Recently, in the letter [Phys. Rev. Lett. 114, 170502 (2015)], Tavakoli et al. derived
interesting results by studying classical and quantum random access codes (RACs) in which …

Communication complexity is a pivotal element in information science, with quantum theory
presenting a significant edge over classical approaches. The standard quantification of one …

The prepare-and-measure scenario offers the possibility to infer the dimension of an
unknown physical system in a device-independent way, ie using only raw measurement …

We explore the fundamental origin of the quantum advantage behind random access code.
We propose new temporal inequalities compatible with noninvasive-realist models and …
