Certifying asymmetry in the configuration of three qubits
Abdelmalek Taoutioui, Gábor Drótos, Tamás Vértesi
Symmetry restrictions limit the types of tasks that can be achieved with a given set of quantum states. Therefore, any breaking of these symmetries could potentially be exploited a…
Unlimited quantum correlation advantage from bound entanglement
Armin Tavakoli, Carles Roch i Carceller, Lucas Tendick +1
Entangled states that cannot be distilled to maximal entanglement are called bound entangled and they are often viewed as too weak to break the limitations of classical models. Her…
How Likely Are You to Observe Non-locality with Imperfect Detection Efficiency and Random Measurement Settings?
Paweł Cieśliński, Tamás Vértesi, Mateusz Kowalczyk +1
Imperfect detection efficiency remains one of the major obstacles in achieving loophole-free Bell tests over long distances. At the same time, the challenge of establishing a commo…
Bound entanglement-assisted prepare-and-measure scenarios based on four-dimensional quantum messages
István Márton, Erika Bene, Tamás Vértesi
We present a class of linear correlation witnesses that detects bound entanglement within a three-party prepare-and-measure scenario with four-dimensional quantum messages. We rela…
