摘要
We present a scheme for perfectly teleporting a two-qubit entangled state via two parallel W state channels.The scheme consists of a positive operator valued measurement(POVM),classical communication and the corresponding local unitary operation.How to realize the POVM using unitary operation and projective measurement is explicitly designed.
