M. J. DuffQuantum entanglement lies at the heart of quantum information theory, with applications to quantum computing, teleportation, cryptography and communication.

Despite their apparent differences, it turns out that there is a correspondence between the two.View original: http://arxiv.org/abs/1206.2105
