In this paper, we
demonstrate n-party controlled
unitary gate implementations locally on arbitrary remote state through linear
entangled channel where control parties share entanglement with the adjacent
control parties and only one of them shares entanglement with the target party.
In such a network, we describe the protocol of simultaneous implementation of
controlled-Hermitian gate starting from three party scenarios.
We also explicate the implementation of three party controlled-Unitary gates, a
generalized form of Toffoli gate and subsequently generalize the protocol for n-party using
