Detecting entanglement of unknown states by violating the Clauser-Horne-Shimony-Holt inequality
J. Cortés-Vega, J. F. Barra, L. Pereira +1
Entangled states play a fundamental role in Quantum Mechanics and are at the core of many contemporary applications, such as quantum communication and quantum computing. Therefore,…
Certifying an irreducible 1024-dimensional photonic state using refined dimension witnesses
Edgar A. Aguilar, Máté Farkas, Daniel Martínez +7
We report on a new class of dimension witnesses, based on quantum random access codes, which are a function of the recorded statistics and that have different bounds for all possib…
Experimental demonstration of the connection between quantum contextuality and graph theory
Gustavo Cañas, Evelyn Acuña, Jaime Cariñe +5
We report a method that exploits a connection between quantum contextuality and graph theory to reveal any form of quantum contextuality in high-precision experiments. We use this…
Device-Independent Certification of a Nonprojective Qubit Measurement
Esteban S. Gómez, Santiago Gómez, Pablo González +8
Quantum measurements on a two-level system can have more than two independent outcomes, and in this case, the measurement cannot be projective. Measurements of this general type ar…
Testing noncontextuality inequalities that are building blocks of quantum correlations
Mauricio Arias, Gustavo Cañas, Esteban S. Gómez +6
Measurement scenarios containing events with relations of exclusivity represented by pentagons, heptagons, nonagons, etc., or their complements are the only ones in which quantum p…
Quantum randomness protected against detection loophole attacks
Piotr Mironowicz, Gustavo Cañas, Jaime Cariñe +6
Device and semi-device independent quantum randomness generators (DI- and SDI-QRNGs) are crucial for applications requiring private randomness. However, they are vulnerable to dete…
Device-independent certification of high-dimensional quantum systems
Vincenzo D'Ambrosio, Fabrizio Bisesto, Fabio Sciarrino +3
An important problem in quantum information processing is the certification of the dimension of quantum systems without making assumptions about the devices used to prepare and mea…
Bell tests with random measurements require very high detection efficiencies
Esteban S. Gómez, Gustavo Cañas, Johanna F. Barra +2
The observation that violating Bell inequalities with high probability is possible even when the local measurements are randomly chosen, as occurs when local measurements cannot be…
A higher quantum bound for the Vértesi-Bene-Bell-inequality and the role of POVMs regarding its threshold detection efficiency
J. F. Barra, E. S. Gómez, G. Cañas +3
Recently, Vértesi and Bene [Phys. Rev. A. {\bf 82}, 062115 (2010)] derived a two-qubit Bell inequality, , which they show to be maximally violated only when more general p…
Detection efficiency for loophole-free Bell tests with entangled states affected by colored noise
Gustavo Cañas, Johanna F. Barra, Esteban S. Gómez +3
Loophole-free Bell tests for quantum nonlocality and long-distance secure communication require photodetection efficiencies beyond a threshold eta_{crit} that depends on the Bell i…
