@article {1601, title = {Quantum Entanglement and Information}, journal = {The Stanford Encyclopedia of Philosophy}, year = {2015}, month = {02/07/2015}, abstract = {Quantum entanglement is a physical resource, like energy, associated with the peculiar nonclassical correlations that are possible between separated quantum systems. Entanglement can be measured, transformed, and purified. A pair of quantum systems in an entangled state can be used as a quantum information channel to perform computational and cryptographic tasks that are impossible for classical systems. The general study of the information-processing capabilities of quantum systems is the subject of quantum information theory.}, url = {http://plato.stanford.edu/archives/sum2015/entries/qt-entangle/}, author = {Jeffrey Bub and Edward N.
