Abstract
We discuss the close connections between cloning of quantum states and supe rluminal signaling. We present an optimal universal cloning machine based o n stimulated emission recently proposed by us. As an instructive example, w e show how a scheme for superluminal communication based on this cloning ma chine fails.
