Generic appearance of objective results in quantum measurements

2017 · Physical Review A

Measurement is of central interest in quantum mechanics as it provides the link between the quantum world and the world of everyday experience. One of the features of everyday experience is its robust, objective character, …

Single trusted qubit is necessary and sufficient for quantum realisation of extremal no-signaling correlations

2020 · arXiv (Cornell University)

Quantum statistics can be considered from the perspective of postquantum no-signaling theories in which either none or only a certain number of quantum systems are trusted. In these scenarios, the role of states is played …

Two instances of random access code in the quantum regime

2023 · New Journal of Physics

Abstract We consider two classes of quantum generalisations of random access code (RAC) and study the bounds for probabilities of success for such tasks. It provides a useful framework for the study of certain information …
