Device-independent and semi-device-independent entanglement certification in broadcast Bell scenarios

open access: yesSciPost Physics Core, 2023
It has recently been shown that by broadcasting the subsystems of a bipartite quantum state, one can activate Bell nonlocality and significantly improve noise tolerance bounds for device-independent entanglement certification.

Guidelines for the LTO Noise Assessment of Future Civil Supersonic Aircraft in Conceptual Design

open access: yesAerospace, 2022
One of the most critical regulatory issues related to supersonic flight arises from limitations imposed by community noise acceptability. The most efficient way to ensure that future supersonic aircraft will meet low-noise requirements is the ...

High-Dimensional Pixel Entanglement: Efficient Generation and Certification [PDF]

open access: yesQuantum, 2020
Photons offer the potential to carry large amounts of information in their spectral, spatial, and polarisation degrees of freedom. While state-of-the-art classical communication systems routinely aim to maximize this information-carrying capacity via ...

Certifying nonlocal properties of noisy quantum operations [PDF]

open access: yesQuantum
Certifying quantum properties from the probability distributions they induce is an important task for several purposes. While this framework has been largely explored and used for quantum states, its extrapolation to the level of channels started ...

Reliable quantum certification for photonic quantum technologies [PDF]

open access: yes, 2015
A major roadblock for large-scale photonic quantum technologies is the lack of practical reliable certification tools. We introduce an experimentally friendly - yet mathematically rigorous - certification test for experimental preparations of arbitrary m-

Comparison of predicted engine core noise with proposd FAA helicopter noise certification requirements [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1981
Calculated engine core noise levels, based on NASA-Lewis prediction procedures, for five representative helicopter engines are compared with measured total helicopter noise levels and proposed FAA helicopter noise certification requirements. Comparisons are made for approach, level flyover, and takeoff procedures.
