Quantum information differs profoundly from classical information by virtue of the properties, implications, and uses of quantum entanglement—the non-separable correlations among parts of a quantum system. John Bell's famous theorem on the incompatibility of quantum mechanics with local hidden-variable theories established that these correlations have no classical counterpart.[1] More recently, new algorithms for quantum computation and communication make clear that quantum entanglement is essential for accomplishing otherwise impossible tasks. Perhaps the most remarkable of such possibilities is class="EmphasisTypeItalic ">quantum teleportation, whereby an unknown quantum state is "disembodied" into quantum and classical components and resurrected at a remote location via quantum entanglement.
