Completely mixed state is a critical point for three-qubit entanglement
Sayatnova Tamaryan
Pure three-qubit states have five algebraically independent and one algebraically dependent polynomial invariants under local unitary transformations and an arbitrary entanglement…

Universal behavior of the geometric entanglement measure of many-qubit W states
Levon Tamaryan, Zaruhi Ohanyan, Sayatnova Tamaryan
We show that when N>>1 the geometric entanglement measure of general N-qubit W states, except maximally entangled W states, is a one-variable function and depends only on the Bloch…

Duality and the geometric measure of entanglement of general multiqubit W states
Sayatnova Tamaryan, Anthony Sudbery, Levon Tamaryan
We find the nearest product states for arbitrary generalized W states of n qubits, and show that the nearest product state is essentially unique if the W state is highly entangled.…
