Geometric Measure of Entanglement and Schmidt Decomposition of Multipartite Systems

Levon Tamaryan

The thesis includes the original results of our articles [30, 37, 40, 42, 51, 53, 75]. A method is developed to compute analytically entanglement measures of three-qubit pure state…

Nonstrict inequality for Schmidt coefficients of three-qubit states

Levon Tamaryan

Generalized Schmidt decomposition of pure three-qubit states has four positive and one complex coefficients. In contrast to the bipartite case, they are not arbitrary and the large…

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.…

Generalized Schmidt decomposition based on injective tensor norm

Levon Tamaryan, DaeKil Park, Sayatnova Tamaryan

We present a generalized Schmidt decomposition for a pure system with any number of two-level subsystems. The basis is symmetric under the permutation of the parties and is derived…

Toward an understanding of entanglement for generalized n-qubit W-states

Levon Tamaryan, Hungsoo Kim, Eylee Jung +3

We solve stationarity equations of the geometric measure of entanglement for multi-qubit W-type states. In this way we compute analytically the maximal overlap of one-parameter …
