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.…

Effect of Phase Factor in the Geometric Entanglement Measure of Three-Qubit States

Sayatnova Tamaryan, Hungsoo Kim, Mu-Seong Kim +2

Any pure three-qubit state is uniquely characterized by one phase and four positive parameters. The geometric measure of entanglement as a function of state parameters can have dif…

Maximally entangled three-qubit states via geometric measure of entanglement

Sayatnova Tamaryan, Tzu-Chieh Wei, DaeKil Park

Bipartite maximally entangled states have the property that the largest Schmidt coefficient reaches its lower bound. However, for multipartite states the standard Schmidt decomposi…

Three-Party Entanglement in Tripartite Teleportation Scheme through Noisy Channels

Eylee Jung, Mi-Ra Hwang, DaeKil Park +1

We have tried to interpret the physical role of the three-tangle and -tangle in the real physical information process. For the model calculation we adopt the three-party telepor…
