Query: Applications of quantum cryptographic switch: Various tasks related to
  controlled quantum communication can be performed using Bell states and
  permutation of particles   Recently, several aspects of controlled quantum communication (e.g.,
bidirectional controlled state teleportation, controlled quantum secure direct
communication, controlled quantum dialogue, etc.) have been studied using
$n$-qubit ($n\geq3$) entanglement. Specially, a large number of schemes for
bidirectional controlled state teleportation are proposed using $m$-qubit
entanglement ($m\in\{5,6,7\}$). Here, we propose a set of protocols to
illustrate that it is possible to realize all these tasks related to controlled
quantum communication using only Bell states and permutation of particles
(PoP). As the generation and maintenance of a Bell state is much easier than a
multi-partite entanglement, the proposed strategy has a clear advantage over
the existing proposals. Further, it is shown that all the schemes proposed here
may be viewed as applications of the concept of quantum cryptographic switch
which was recently introduced by some of us. The performances of the proposed
protocols as subjected to the amplitude damping and phase damping noise on the
channels are also discussed.
