  Quantum communications require efficient implementations of quantum state
transportation with high fidelity. Here, we consider the transport of
entanglement along a chain of qubits. A series of SWAP operations involving
successive pairs of qubits can transport entanglement along the chain. We
report that the fidelity of the abovementioned gate has a maximum value
corresponding to an optimum value of the drive amplitude in the presence of
drive-induced decoherence. To incorporate environmental effect, we use a
previously reported fluctuation-regulated quantum master equation [A.
Chakrabarti and R. Bhattacharyya, Phys. Rev. A 97, 063837 (2018)]. The
existence of an optimum drive amplitude implies that these series of SWAP
operations on open quantum systems would have an optimal transfer speed of the
entanglement.
