ferromagnetic spin chain have been investigated. New cooling techniques [@Medley2010] have enabled, reaching for the first time, the temperatures required for observing quantum magnetic phases emerged due to spin interactions. In view of these, it is very timely to put forward new proposals which are doable with current achievements in cold atom experiments. In particular, one may think of new ways for quantum communication across a strongly correlated many-body interacting systems.

In this paper, we introduce a mechanism for exploiting the inherent entanglement of many-body systems for quantum communication across a spin chain. The encoding of information is done through a single qubit measurement followed by the operation of a unitary gate which is determined by the random outcome of the measurement. The following measurement induced dynamics propagates the quantum state through the chain till it reaches the other side in which the information is captured by switching off the interaction couplings. The proposed protocol, which has been inspired by recent achievements for observing spin waves in ferromagnetic chains in optical lattices [@Bloch-spin-wave; @Bloch-magnon], exploits quantum measurement in order to induce quench dynamics in the system and can be seen as the first step for observing spin dynamics in anti-ferromagnetic
