Quantum steering

R Uola, ACS Costa, HC Nguyen, O Gühne - Reviews of Modern Physics, 2020 - APS
Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

Colloquium: Incompatible measurements in quantum information science

O Gühne, E Haapasalo, T Kraft, JP Pellonpää… - Reviews of Modern …, 2023 - APS
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 …

Quantum steering: a review with focus on semidefinite programming

D Cavalcanti, P Skrzypczyk - Reports on Progress in Physics, 2016 - iopscience.iop.org
Quantum steering refers to the non-classical correlations that can be observed between the
outcomes of measurements applied on half of an entangled state and the resulting post …

Quantum fidelity measures for mixed states

YC Liang, YH Yeh, PEMF Mendonça… - Reports on Progress …, 2019 - iopscience.iop.org
Applications of quantum technology often require fidelities to quantify performance. These
provide a fundamental yardstick for the comparison of two quantum states. While this is …

Quantum steering: Practical challenges and future directions

Y Xiang, S Cheng, Q Gong, Z Ficek, Q He - PRX Quantum, 2022 - APS
Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the “spooky action
at a distance” that one party is able to remotely alter the states of the other if they share a …

All sets of incompatible measurements give an advantage in quantum state discrimination

P Skrzypczyk, I Šupić, D Cavalcanti - Physical review letters, 2019 - APS
Some quantum measurements cannot be performed simultaneously; ie, they are
incompatible. Here we show that every set of incompatible measurements provides an …

Quantifying Bell: The resource theory of nonclassicality of common-cause boxes

E Wolfe, D Schmid, AB Sainz, R Kunjwal… - Quantum, 2020 - quantum-journal.org
We take a resource-theoretic approach to the problem of quantifying nonclassicality in Bell
scenarios. The resources are conceptualized as probabilistic processes from the setting …

Semidefinite programming relaxations for quantum correlations

A Tavakoli, A Pozas-Kerstjens, P Brown… - arXiv preprint arXiv …, 2023 - arxiv.org
Semidefinite programs are convex optimisation problems involving a linear objective
function and a domain of positive semidefinite matrices. Over the last two decades, they …

Genuine high-dimensional quantum steering

S Designolle, V Srivastav, R Uola, NH Valencia… - Physical Review Letters, 2021 - APS
High-dimensional quantum entanglement can give rise to stronger forms of nonlocal
correlations compared to qubit systems, offering significant advantages for quantum …

Entanglement and superposition are equivalent concepts in any physical theory

G Aubrun, L Lami, C Palazuelos, M Plávala - Physical Review Letters, 2022 - APS
We prove that given any two general probabilistic theories (GPTs) the following are
equivalent:(i) each theory is nonclassical, meaning that neither of their state spaces is a …
