Criterion for faithful teleportation with an arbitrary multiparticle channel
Chi-Yee Cheung, Zhanjun Zhang · Physical Review A · 2009
We present a general criterion which allows one to judge if an arbitrary multiparticle entanglement channel can be used to teleport faithfully an unknown quantum state of a given dimension. We also present a general multiparticle teleportation protocol which is applicable for all channel states satisfying this criterion.
