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 …

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 …

Quantum entanglement and non-locality are two special aspects of quantum correlations.
The relationship between multipartite entanglement and non-locality is at the root of the …

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 …

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 …

The aim of this thesis is to understand the fundamental limitations on secret key distillation in
various settings of quantum key distribution. We first consider quantum steering, which is a …

One of the main goals in the study of quantum nonlocality is to determine the maximum
violation achieved by quantum correlations in a Bell scenario. However, given a Bell …
