Abstract： We discuss teleportation of unitary operations on a two-qubit in detail, then generalize the bidirectional state teleportation scheme from one-qubit to M-qubit unitary operations. The resources required for optimal implementation of teleportation of an M-qubit unitary operation by using bidirectional state teleportation scheme are given.
