Towards minimal self-testing of qubit states and measurements in prepare-and-measure scenarios
Gábor Drótos, Károly F. Pál, Abdelmalek Taoutioui +1
Self-testing is a promising approach to certifying quantum states or measurements. Originally, it relied solely on the outcome statistics of the measurements involved in a device-i…
Disproving hidden variable models with spin magnitude conservation
Pawel Kurzynski, Wieslaw Laskowski, Adrian Kolodziejski +3
The squares of the three components of the spin-s operators sum up to . However, a similar relation is rarely satisfied by the set of possible spin projections onto mutuall…
Family of Bell inequalities violated by higher-dimensional bound entangled states
Karoly F Pal, Tamas Vertesi
We construct ()-dimensional bound entangled states, which violate, for any , a bipartite Bell inequality introduced in this paper. We conjecture that the proposed c…
Bell inequalities violated using detectors of low efficiency
Karoly F. Pal, Tamas Vertesi
We define a family of binary outcome -party settings per party Bell inequalities whose members require the least detection efficiency for their violation among all kno…
Closing the detection loophole in tripartite Bell tests using the W state
Karoly F. Pal, Tamas Vertesi
We study the problem of closing the detection loophole in three-qubit Bell tests, the experimentally most relevant case beyond the usual bipartite scenario, and show that the minim…
Device-independent tomography of multipartite quantum states
Karoly F. Pal, Tamas Vertesi, Miguel Navascues
In the usual tomography of multipartite entangled quantum states one assumes that the measurement devices used in the laboratory are under perfect control of the experimenter. In t…
