Fundamental limits on key rates in device-independent quantum key distribution
In this paper, we introduce intrinsic non-locality and quantum intrinsic non-locality as
quantifiers for Bell non-locality, and we prove that they satisfy certain desirable properties …

Upper bounds on device-independent quantum key distribution
Quantum key distribution (QKD) is a method that distributes a secret key to a sender and a
receiver by the transmission of quantum particles (eg, photons). Device-independent …

Positive tensor products of maps and n-tensor-stable positive qubit maps
SN Filippov, KY Magadov - Journal of Physics A: Mathematical …, 2017 - iopscience.iop.org
We analyze positivity of a tensor product of two linear qubit maps, ${{\Phi} _ {1}}\otimes
{{\Phi} _ {2}} $. Positivity of maps ${{\Phi} _ {1}} $ and ${{\Phi} _ {2}} $ is a necessary but not a …

Family of Bell inequalities violated by higher-dimensional bound entangled states
KF Pál, T Vértesi - Physical Review A, 2017 - APS
We construct (d× d)-dimensional bound entangled states, which violate, for any d> 2, a
bipartite Bell inequality introduced in this paper. We conjecture that the proposed class of …

Bounds on quantum nonlocality
G Murta - arXiv preprint arXiv:1704.04922, 2017 - arxiv.org
One of the main goals in the study of quantum nonlocality is to determine the maximum
