Teleporting an unknown quantum state via dual classical and EinsteinPodolskyRosen channels
Abstract
An unknown quantum state φ> can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical EinsteinPodolskyRosen (EPR) correlations. To do so the sender, ``Alice,'' and the receiver, ``Bob,'' must prearrange the sharing of an EPRcorrelated 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.
