Guaranteed violation of a Bell inequality without aligned reference frames or calibrated devices
Peter Shadbolt, Tamas Vertesi, Yeong-Cherng Liang +3
Bell tests---the experimental demonstration of a Bell inequality violation---are central to understanding the foundations of quantum mechanics, underpin quantum technologies, and a…
Testing the Structure of Multipartite Entanglement with Bell Inequalities
Nicolas Brunner, James Sharam, Tamas Vertesi
We show that the rich structure of multipartite entanglement can be tested following a device-independent approach. Specifically we present Bell inequalities for distinguishing bet…
More non-locality in the three-qubit Greenberger-Horne-Zeilinger state
Tamas Vertesi, Karoly F. Pal
The non-local properties of the noisy three-qubit Greenberger-Horne-Zeilinger (GHZ) states parameterized by the visibility 0<v<1 are investigated. Based on the violation of the 2x2…
Quantum nonlocality does not imply entanglement distillability
Tamas Vertesi, Nicolas Brunner
Entanglement and nonlocality are both fundamental aspects of quantum theory, and play a prominent role in quantum information science. The exact relation between entanglement and n…
Multisetting Bell-type inequalities for detecting genuine tripartite entanglement
Karoly F. Pal, Tamas Vertesi
In a recent paper, Bancal et al. put forward the concept of device-independent witnesses of genuine multipartite entanglement. These witnesses are capable of verifying genuine mult…
Certifying entangled measurements in known Hilbert spaces
Tamas Vertesi, Miguel Navascues
We study under which conditions it is possible to assert that a joint demolition measurement cannot be simulated by Local Operations and Classical Communication. More concretely, w…
