Geometric measure of entanglement for multipartite quantum states
Tzu-Chieh Wei, Paul M. Goldbart
The degree to which a pure quantum state is entangled can be characterized by the distance or angle to the nearest unentangled state. This geometric measure of entanglement, alread…

Maximal entanglement versus entropy for mixed quantum states
Tzu-Chieh Wei, Kae Nemoto, Paul M. Goldbart +3
Maximally entangled mixed states are those states that, for a given mixedness, achieve the greatest possible entanglement. For two-qubit systems and for various combinations of ent…
