  Quantum states can be efficiently transferred over a long distance if the
entire quantum channel can be divided into several small blocks. We consider a
scenario in which each block consists of two copies of a multiparty state --
one is used for distributing an arbitrary quantum state to multiple parties
while the other channel is required to concentrate it back to a single party.
Both in noiseless and local noisy scenarios, we find one-shot quantum
capacities of these channels in terms of fidelity, when the initial shared
states in each block are the generalized Greenberger-Horne-Zeilinger and the
generalized W states. We also consider a situation where optimal local
measurements transform multipartite states to bipartite ones which can then be
used as single-path channels for quantum state transmission in each segment. We
show that in some parameter ranges, the former protocol provides strictly
better fidelities than that of the latter, thereby establishing the importance
of distributing and concentrating arbitrary quantum states via multipartite
entangled states in long distance quantum communication, over the local
measurement based protocol. Moreover, we show that in presence of bit flip or
bit-phase flip noise, shared generalized Greenberger-Horne-Zeilinger states
possess an inherent noise detection and correction mechanism, leading to the
same fidelity as in the noiseless case. We consider further noise models also,
which do not enjoy the same mechanism. In addition to the fidelity based
advantages, the multipath scheme is shown to be useful when one considers a
situation in which the completion of the teleportation needs to be delayed. We
also find the efficiencies of a quantum channel when a quantum state is
transferred over long distances and the entire channel is divided into several
small blocks.
