Effect of pure phase decoherence on entanglement teleportation
M. Ge, Linbo Zhu, Liang Qiu · Annalen der Physik · 2008
Abstract We study entanglement teleportation in the two‐qubit XX Heisenberg model with pure phase decoherence taken into account. For some initial entangled states, pure phase decoherence has no effect on the teleported entanglement, while for others pure phase decoherence has a pronounced effect. In addition, entanglement sudden death happens in the latter case.
