  Entangled states can be used as secure carriers of information much in the
same way as carriers are used in classical communications. In such protocols,
quantum states are uploaded to the carrier at one end and are downloaded from
it in safe form at the other end, leaving the carrier intact and ready for
reuse. Furthermore, protocols have been designed for performing quantum state
sharing in this way. In this work, we study the robustness of these protocols
against noise and show that multiple uses of these carriers do not lead to
accumulative errors, rather the error remains constant and under control.
