  Qubit(s) transfer through a helical chain is studied. We consider the
transfer of a single state and Bell states across a multiferroic spin chain and
the possibility of an electric field control of the fidelity of the single
state and the Bell pairs. We analyze pure and imperfect multiferroic spin
chains. A scheme for an efficient transfer of spin states through a
multiferroic channel relies on kicking by appropriate electric field pulses at
regular interval. This electric field pulse sequence undermines the effect of
impurity on the fidelity and improves the state transfer through the helical
chain.
