Magnetic Properties and Thermal Entanglement on a Triangulated Kagome Lattice
N. S. Ananikian, L. N. Ananikyan, L. A. Chakhmakhchyan +1
The magnetic and entanglement thermal (equilibrium) properties in spin-1/2 Ising-Heisenberg model on a triangulated Kagome lattice are analyzed by means of variational mean-field l…
Transferring elements of a density matrix
Armen E. Allahverdyan, Karen V. Hovhannisyan
We study restrictions imposed by quantum mechanics on the process of matrix elements transfer. This problem is at the core of quantum measurements and state transfer. Given two sys…
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.…
