摘要：
A nontrivial protocol for teleporting an unknown N-qubit W-like state is proposed. The consumed resource is only (N-1) shared ebits and 2(N-1) bits of classical communication, while the technique involves only controlled-NOT gates and single-qubit measurements/operations. The rule for reconstruction of the desired state at the receiving station is worked out explicitly in the most general case of an arbitrary N >= 3. The protocol is within the reach of present technologies.
