Partial separability and entanglement criteria for multiqubit quantum states
Michael Seevinck, Jos Uffink
We explore the subtle relationships between partial separability and entanglement of subsystems in multiqubit quantum states and give experimentally accessible conditions that dist…
Local commutativity versus Bell inequality violation for entangled states and versus non-violation for separable states
Michael Seevinck, Jos Uffink
By introducing a quantitative `degree of commutativity' in terms of the angle between spin-observables we present two tight quantitative trade-off relations in the case of two qubi…
Strengthened Bell inequalities for orthogonal spin directions
J. Uffink, M. Seevinck
We strengthen the bound on the correlations of two spin-1/2 particles (qubits) in separable (non-entangled) states for locally orthogonal spin directions by much tighter bounds tha…
Addendum to "Sufficient conditions for three-particle entanglement and their tests in recent experiments"
Geza Toth, Otfried Guehne, Michael Seevinck +1
A recent paper [M. Seevinck and J. Uffink, Phys. Rev. A 65, 012107 (2002)] presented a bound for the three-qubit Mermin inequality such that the violation of this bound indicates g…
Quadratic Bell inequalities as tests for multipartite entanglement
Jos Uffink
This letter presents quantum mechanical inequalities which distinguish, for systems of spin-$\half$ particles (), between fully entangled states and states in which at mos…
Sufficient conditions for three-particle entanglement and their tests in recent experiments
Michael Seevinck, Jos Uffink
We point out a loophole problem in some recent experimental claims to produce three-particle entanglement. The problem consists in the question whether mixtures of two-particle ent…
