Algorithmic construction of local hidden variable models for entangled quantum states
Flavien Hirsch, Marco Túlio Quintino, Tamás Vértesi +2
Constructing local hidden variable (LHV) models for entangled quantum states is challenging, as the model should reproduce quantum predictions for all possible local measurements.…
Bond dimension witnesses and the structure of homogeneous matrix product states
Miguel Navascues, Tamas Vertesi
For the past twenty years, Matrix Product States (MPS) have been widely used in solid state physics to approximate the ground state of one-dimensional spin chains. In this paper, w…
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…
Characterizing finite-dimensional quantum behavior
Miguel Navascues, Adrien Feix, Mateus Araujo +1
We study and extend the semidefinite programming (SDP) hierarchies introduced in [Phys. Rev. Lett. 115, 020501] for the characterization of the statistical correlations arising fro…
Postquantum steering
Ana Belen Sainz, Nicolas Brunner, Daniel Cavalcanti +2
The discovery of postquantum nonlocality, i.e., the existence of nonlocal correlations that are stronger than any quantum correlations but nevertheless consistent with the no-signa…
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…
