Symmetry breaking effects upon bipartite and multipartite entanglement in the XY model
Thiago R. de Oliveira, Gustavo Rigolin, Marcos C. de Oliveira +1
We analyze the bipartite and multipartite entanglement for the ground state of the one-dimensional XY model in a transverse magnetic field in the thermodynamical limit. We explicit…
Generalized Quantum Telecloning
Goren Gordon, Gustavo Rigolin
We present a generalized telecloning (GTC) protocol where the quantum channel is non-optimally entangled and we study how the fidelity of the telecloned states depends on the entan…
Superdense coding using multipartite states
G. Rigolin
We show that with the fourpartite quantum channel used to teleport an arbitrary two qubit state, we can construct a superdense coding protocol where it is possible to transmit 4 bi…
Thermal entanglement in the two-qubit Heisenberg XYZ model
G. Rigolin
We study the entanglement of a two-qubit one dimensional XYZ Heisenberg chain in thermal equilibrium at temperature T. We obtain an analytical expression for the entanglement of fo…
