Graph-theoretic approach to dimension witnessing
(IOP Publishing, 2021-03)
A fundamental problem in quantum computation and quantum information is finding the minimum quantum dimension needed for a task. For tasks involving state preparation and measurements, this problem can be addressed using ...

Quantum key distribution without alternative measurements
(American Physical Society, 2000-04-18)
Entanglement swapping between Einstein-Podolsky-Rosen (EPR) pairs can be used to generate the same sequence of random bits in two remote places. A quantum key distribution protocol based on this idea is described. The ...

Acoustic ambience and simulation of the bullring of Ronda (Spain)
(MDPI, 2024-01-22)
The bullring of Ronda, one of the oldest in Spain, declared in 1993 as an Asset of Cultural Interest, occupies a paramount place among the buildings of its type thanks to its outstanding beauty. Its configuration as an ...

Quantum contextuality provides communication complexity advantage
(American Physical Society, 2023-02-24)
Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement. Here, we show that for any quantum state and observables ...

Efficiency calibration and optimization of a liquid scintillation spectrometer for low level 55Fe and 63Ni measurements
(Elsevier, 2023-11)
An experimental study on the counting efficiency, background, and Lower Limit of Detection (LLD) of a liquid scintillation spectrometer was carried out for establishing a measurement technique suitable for low level activity ...

Graph-theoretic approach to Bell experiments with low detection efficiency
(Cornell University, 2023)
Bell inequality tests where the detection efficiency is below a certain threshold ηcrit can be simulated with local hidden-variable models. For the Clauser-Horne-Shimony-Holt Bell inequality and maximally entangled states, ...

A comparison of 210Pbxs, 137Cs, and Pu isotopes as proxies of soil redistribution in South Spain under severe erosion conditions
(Springer, 2023-06-01)
Purpose The use of fallout radionuclides as proxies for the study of soil redistribution processes in semiarid environments of Southern Spain has been restricted to 137Cs. The potential and limitations of alternative ...
