Self-testing of quantum systems: a review

I Šupić, J Bowles - Quantum, 2020 - quantum-journal.org
Self-testing is a method to infer the underlying physics of a quantum experiment in a black
box scenario. As such it represents the strongest form of certification for quantum systems. In …

Calibration-independent bound on the unitarity of a quantum channel with application to a frequency converter

underlying physics of quantum experiments in a black-box scenario. Numerous …

Bell inequality violations with random mutually unbiased bases

GNM Tabia, VSR Bavana, SX Yang, YC Liang - Physical Review A, 2022 - APS
We examine the problem of exhibiting Bell nonlocality for a two-qudit entangled pure state
using a randomly chosen set of mutually unbiased bases (MUBs). Interestingly, even if we …

S Storz, A Kulikov, JD Schär, V Barizien… - arXiv preprint arXiv …, 2024 - arxiv.org
Self-testing protocols enable the certification of quantum systems in a device-independent
manner, ie without knowledge of the inner workings of the quantum devices under test …

Tilted Hardy paradoxes for device-independent randomness extraction

S Zhao, R Ramanathan, Y Liu, P Horodecki - Quantum, 2023 - quantum-journal.org
The device-independent paradigm has had spectacular successes in randomness
generation, key distribution and self-testing, however most of these results have been …

Experimental demonstration of one-sided device-independent self-testing of any pure two-qubit entangled state

Z Bian, AS Majumdar, C Jebarathinam, K Wang, L Xiao… - Physical Review A, 2020 - APS
We demonstrate one-sided device-independent self-testing of any pure two-qubit entangled
state based on a fine-grained steering inequality. The maximum violation of a fine-grained …

How post-selection affects device-independent claims under the fair sampling assumption

D Orsucci, JD Bancal, N Sangouard, P Sekatski - Quantum, 2020 - quantum-journal.org
Device-independent certifications employ Bell tests to guarantee the proper functioning of
an apparatus from the sole knowledge of observed measurement statistics, ie without …

Interplay among entanglement, measurement incompatibility, and nonlocality

Y Zhu, X Zhang, X Ma - Quantum Science and Technology, 2024 - iopscience.iop.org
Nonlocality, manifested by the violation of Bell inequalities, indicates entanglement within a
joint quantum system. A natural question is how much entanglement is required for a given …
