  Telecloning and its reverse process, referred to as remote information
concentration(RIC), have attracted considerable interest because of their
potential applications in quantum-information processing. We here present a
general scheme for RIC in d-level systems (qudits), in which the quantum
information initially distributed in many spatially separated qudits can be
remotely and deterministically concentrated to a single qudit via an entangled
channel without performing any global operations. We show that the entangled
channel of RIC can be different types of entangled states, including mixed
states as well as pure ones. More interestingly, these mixed states include a
bound entangled state which has a similar form to the generalized Smolin state
but has different characteristics from it. We also show that there exists a
multipartite entangled state which can be used to implement both telecloning
and RIC in the two-level system. Our many-to-one RIC protocol could be slightly
modified to perform some types of many-to-many RIC tasks.
