Query: Selective dynamical decoupling for quantum state transfer   State transfer across discrete quantum networks is one of the elementary
tasks of quantum information processing. Its aim is the faithful placement of
information into a specific position in the network. However, all physical
systems suffer from imperfections, which can severely limit the transfer
fidelity. We present selective dynamical decoupling schemes which are capable
of stabilizing imperfect quantum state transfer protocols on the model of a
bent linear qubit chain. The efficiency of the schemes is tested and verified
in numerical simulations on a number of realistic cases. The simulations
demonstrate that these selective dynamical decoupling schemes are capable of
suppressing unwanted errors in quantum state transfer protocols efficiently.
