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.1 aBub, Jeffrey1 aZalta, Edward, N.  uhttp://plato.stanford.edu/archives/sum2015/entries/qt-entangle/
