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…
