### Abstract

We consider the problem of teleporting superposed coherent state using
nonmaximally entangled coherent state (NMECS) as quantum channel and study the
effect of entanglement on the quality of teleportation. Based on the amount of
entanglement shared between the sender and the receiver, we propose two unitary
operation strategies to be adopted by the receiver to recover replica of
information state with as large a fidelity as possible, and
analyzed the behavior
of minimum average fidelity (MAF) and mean fidelity (MF) with respect to
entanglement. It is fascinatingly
found that if the maximally entangled coherent state used in previously proposed
schemes is replaced by a particular NMECS, MAF of quantum teleportation
increases appreciably at small coherent
amplitudes. For coherent amplitudes
