Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels

An unknown quantum state 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-correlat...

Description
Summary:An unknown quantum state 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 quantum state which Alice destroyed. (Author)
