Beating one bit of communication with and without quantum pseudo-telepathy
István Márton, Erika Bene, Péter Diviánszky +1
According to Bell's theorem, certain entangled states cannot be simulated classically using local hidden variables (LHV). But if can we augment LHV by classical communication, how…
Certification of qubits in the prepare-and-measure scenario with large input alphabet and connections with the Grothendieck constant
Péter Diviánszky, István Márton, Erika Bene +1
We address the problem of testing the quantumness of two-dimensional systems in the prepare-and-measure (PM) scenario, using a large number of preparations and a large number of me…
Cyclic Einstein-Podolsky-Rosen Steering
István Márton, Sándor Nagy, Erika Bene +1
Einstein-Podolsky-Rosen (EPR) steering is a form of quantum correlation that exhibits a fundamental asymmetry in the properties of quantum systems. Given two observers, Alice and B…
Bounding the detection efficiency threshold in Bell tests using multiple copies of the maximally entangled two-qubit state carried by a single pair of particles
István Márton, Erika Bene, Tamás Vértesi
In this paper, we investigate the critical efficiency of detectors to observe Bell nonlocality using multiple copies of the maximally entangled two-qubit state carried by a single…
Bound entangled singlet-like states for quantum metrology
Károly F. Pál, Géza Tóth, Erika Bene +1
Bipartite entangled quantum states with a positive partial transpose (PPT), i.e., PPT entangled states, are usually considered very weakly entangled. Since no pure entanglement can…
Anion and cation emission from water molecules after collisions with 6.6-keV O ions
Zoltán Juhász, Béla Sulik, Elie Lattouf +9
Anion and cation emission following water dissociation was studied for 6.6-keV O + HO collisions. Absolute cross sections for the emission of all positively and…
