Physics Department, The University of Michigan, Ann Arbor, Michigan 48109-1040, USA(Dated: August 16, 2011)Analyses of phenomena exhibiting finite-time decay of quantum entanglement have recently attracted con-siderable attention. Such decay is often referred to as sudden vanishing (or sudden death) of entanglement,which can be followed by its sudden reappearance (or sudden rebirth). We analyze various finite-time decays(for dissipative systems) and analogous periodic vanishings (for unitary… Expand

Statistical mixtures of states can be more quantum than their superpositions: Comparison of nonclassicality measures for single-qubit states
A bosonic state is commonly considered nonclassical (or quantum) if its Glauber-Sudarshan $P$ function is not a classical probability density, which implies that only coherent states and theirExpand

TLDR
This thesis is focused on giving a proposal of a theoretical recipe for constructing experimentally achievable procedures for the study of quantum correlations and finding operational and practical criteria to classify states in terms of nonclassicality and entanglement based on fundamental classical inequalities like Cauchy-Schwarz inequality.

It is shown that every generic nonclassical state can be detected by a polynomial that is a sum-of-squares of other polynomials, and a family of classicality criteria is derived that requires that the averages of positive functions calculated using P representation must be positive. Expand
