Quantum Phase Transitions and Matrix Product States in Spin Ladders
M. Asoudeh, V. Karimipour, A. Sadrolashrafi
We investigate quantum phase transitions in ladders of spin 1/2 particles by engineering suitable matrix product states for these ladders. We take into account both discrete and co…
Reply to Entanglement split: "Comment on quantum secret sharing based on reusable Greenbergr-Horne-Zeilinger states as secure carriers"
V. Karimipour
In a recent comment, it has been shown that in a quantum secret sharing protocol proposed in [S. Bagherinezhad, V. Karimipour, Phys. Rev. {\bf A}, 67, 044302, (2003)], one of the r…
Thermal entanglement of spins in mean-field clusters
M. Asoudeh, V. Karimipour
We determine thermal entanglement in mean field clusters of spin one-half particles interacting via the anisotropic Heisenberg interaction, with and without external magnetic f…
Dynamics of entanglement of bosonic modes on symmetric graphs
F. Ghahhari, V. Karimipour, R. Shahrokhshahi
We investigate the dynamics of an initially disentangled Gaussian state on a general finite symmetric graph. As concrete examples we obtain properties of this dynamics on mean fiel…
Transition behavior in the capacity of correlated-noisy channels in arbitrary dimensions
V. Karimipour, L. Memarzadeh
We construct a class of quantum channels in arbitrary dimensions for which entanglement improves the performance of the channel. The channels have correlated noise and when the lev…
