Multigraph approach to quantum non-locality
(IOP Publishing, 2014-10-08)
Non-contextuality (NC) and Bell inequalities can be expressed as bounds Ω for positive linear combinations S of probabilities of events, S≤Ω. Exclusive events in S can be represented as adjacent vertices of a graph called ...

El puzle de la teoría cuántica. ¿Es posible zanjar científicamente el debate sobre la naturaleza del mundo cuántico?
(Prensa Científica, 2017)
La mecánica cuántica choca con algunas de nuestras intuiciones más arraigadas acerca del mundo físico. A lo largo de la historia, esa situación ha generado un continuo debate acerca de su significado. Un enfoque tradicional ...

Experimental implementation of a Kochen-Specker Set of Quantum Tests
(American Physical Society, 2013)
The conflict between classical and quantum physics can be identified through a series of yes-no tests onquantum systems, without it being necessary that these systems be in special quantum states. Kochen-Specker (KS) sets ...

All-versus-nothing proof of Einstein-Podolsky-Rosen steering
(Nature Research, 2013-07-05)
Einstein-Podolsky-Rosen steering is a form of quantum nonlocality intermediate between entanglement and Bell nonlocality. Although Schro¨dinger already mooted the idea in 1935, steering still defies a complete understanding. ...

Sustained state-independent quantum contextual correlations from a single ion
(American Physical Society, 2018-05)
We use a single trapped-ion qutrit to demonstrate the quantum-state-independent violation of noncontextuality inequalities using a sequence of randomly chosen quantum nondemolition projective measurements. We concatenate ...

Einstein-Podolsky-Rosen steering is a form of quantum nonlocality intermediate between entanglement and Bell nonlocality. Although Schro¨dinger already mooted the idea in 1935, steering still defies a complete understanding. ...

Single-photon quantum contextuality on a chip
(American Chemical Society, 2017-10-17)
In classical physics, properties of objects exist independently of the context, i.e., whether and how measurements are performed. Quantum physics showed this assumption to be wrong, and that Nature is indeed “contextual”. ...

Experimental observation of quantum state-independent contextuality under no-signaling conditions
(OSA Publishing, 2018-01)
Contextuality, the impossibility of assigning context-independent measurement outcomes, is a critical resource for quantum computation and communication. No-signaling betweensuccessivemeasurementsisanessentialrequirement ...

Quantum correlations from simple assumptions
(American Physical Society, 2019-09-24)
We address the problem of deriving the set of quantum correlations for every Bell and Kochen-Specker (KS) contextuality scenario from simple assumptions. We show that the correlations that are possible according to quantum ...
