An unknown quantum state ‖φ〉 can be disassembled into; then later reconstructed from; purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations. To do so the sender; ‘‘Alice;’’ and the receiver; ‘‘Bob;’’ must prearrange the sharing of an EPR-correlated pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum system; and sends Bob the classical result of this measurement. Knowing this; Bob can convert the state of his EPR particle into an exact replica of the unknown state ‖φ〉 which Alice destroyed.
