Abstract We present a linear optical implementation for quantum teleportation of an unknown two-qubit entangled state by using linear optical elements, such as beam splitters, phase shifters, and half wave plates. This method is based on the single photon representation of quantum bits. Four location qubits and one polarization qubit are used to realize quantum logical operations in the teleportation procedure of the unknown two-qubit entangled state.
