Abstract: | We discuss the aspects of non-locality and nonseparability of states of composite quantum systems. The probabilistic nature of quantum mechanical predictions, and the impossibility of cloning, are shown to safeguard causality in the quantum world. An example of a game which can be won exploiting quantum entanglement, but which can never be won classically, is described. |
