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 …

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 …

Multidimensional quantum entanglement with large-scale integrated optics

J Wang, S Paesani, Y Ding, R Santagati, P Skrzypczyk… - Science, 2018 - science.org

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 …

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

Maximal randomness generation from steering inequality violations using qudits

P Skrzypczyk, D Cavalcanti - Physical Review Letters, 2018 - APS
We consider the generation of randomness based upon the observed violation of an
Einstein-Podolsky-Rosen (EPR) steering inequality, known as one-sided device …

Genuine Einstein-Podolsky-Rosen steering of three-qubit states by multiple sequential observers

S Gupta, AG Maity, D Das, A Roy, AS Majumdar - Physical Review A, 2021 - APS
We investigate the possibility of multiple uses of a single copy of a three-qubit state for
detecting genuine tripartite Einstein-Podolsky-Rosen (EPR) steering. A pure three-qubit …

Rigidity of quantum steering and one-sided device-independent verifiable quantum computation

A Gheorghiu, P Wallden, E Kashefi - New Journal of Physics, 2017 - iopscience.iop.org
The relationship between correlations and entanglement has played a major role in
understanding quantum theory since the work of Einstein et al (1935 Phys. Rev. 47 777–80) …

Quantifying quantumness of channels without entanglement

HY Ku, J Kadlec, A Černoch, MT Quintino, W Zhou… - PRX Quantum, 2022 - APS
Quantum channels breaking entanglement, incompatibility, or nonlocality are defined as
such because they are not useful for entanglement-based, one-sided device-independent …

Demonstration of simultaneous quantum steering by multiple observers via sequential weak measurements

YH Choi, S Hong, T Pramanik, HT Lim, YS Kim, H Jung… - Optica, 2020 - opg.optica.org
Quantum correlation is a fundamental resource for various quantum information tasks. It is
